What is cnc router cutter

A computer numerically controlled (CNC) router cutter is a complex cutting machine that uses a large work area, a cutter, and an electronic computerized component to perform automated cutting techniques. The purpose of a CNC router cutter is to cut different materials, such as wood or metal, in an automated fashion with little help from a person. There are different types of routers that are used for certain purposes based on the field of study or discipline. Even hobbyists use the router and CNC machine to craft pieces of material for projects. The CNC router cutter is used for industrial and manufacturing purposes as well.

All types of CNC equipment, software, electronics and some electronic equipment in order to perform the automatic control of them. The two components of the mechanical systems. The cutting machine, CNC router, the precision in the cut of whatever is being used. Blades traditionally have the ability to create complex shapes by moving a portion of the cut in three-axis direction, including along the axis X, Y axis and Z - the trim along the X axis is the length along. Y-axis is along the z axis is widthwise and up and down.


The key cutting machine, CNC router and the computer systems and control, bed and drive off in a straight line. Cut router system and controls the operation of a motor drive system to rotate in the direction of cutting the material in some fashion. Core cutting machine, CNC router, not the physical act of cutting with router bits of different sizes and operate at varying speeds and horsepower. A router is a living room off the computer, for securing materials in place, and sometimes acts as a guide for cutting the core. Drive system with components that move along the axis, and working with computer systems and controls.



One type of machine that employs cutting machine, CNC router is a device equipped with an automatic ground by a vertical structure. It has a set of cutters, CNC routers, computers, auto parts, cut into thin sheets. These elements are the same computer to get their information from the control at a certain distance away, and operated by third parties. The material can be cut linoleum or plastic.

Cnc Turning Process - an Overview

CNC Turning process is a simple method of shaping a metal or wood on a lathe. It is a machine tool that spins or turns a block of material to achieve rotational symmetry in a machine shop. Turning can be done manually or using a CNC machining. The computer numerically controls CNC machine. A typical CNC machining center is designed to remove material using a rotating cutter that moves laterally to a work piece mounted onto a table or fixture.

In the CNC turning process, a piece of material is rotated on the lathe and a cutting tool is traversed along two axis of motion, transverse or longitudinal. The process is done in a machine shop. The cutting tool is used until the required depth and dimension is achieved. Turning can be on both sides, inside or outside as per the needs and specifications. The rotation occurs at the turning center that enables control of tool motion through computer programs that use numeric data. Parts that are too large to balance and cause difficulty in rotating around one center point, can be worked on a machining center featuring a U axis. The turning length is about 1000mm between centers and has a drive power and speed range up to 46kW and 4,000 revolution/minute respectively.

CNC Turning Process
CNC turning process cuts the metal into various different shapes ranging from plain surface, taper ends, contour, and filter to radius profiles and threaded surfaces. These cut and turned metal pieces are used to create shafts, rods, hubs, bushes, pulleys and much more. Many industries also use it for fabricating parts and materials that have circular cross section. The process applies well to the most rigid materials that can be controlled exclusively with the software program tooling. The process does reduce the cost of production but on the other end, it limits the design flexibility.

CNC Turning Machine
CNC turning machines are said to deliver components at a faster production rate with optimum manufacturing accuracy. The automation of the CNC turning process allows reaching tight dimensional tolerances in every piece. Other advantages are high level of parts consistency or uniformity, achievement of optimum cycle times for all components and faster execution of larger volume. As machines have brought a revolution in the industrial world, new technologies provided by emachineshop, boost the use of metal products.

What is cnc punch press

A CNC punch press is an automated production machine used to form or punch out pre-determined shapes from thin stock material. CNC stands for Computer Numerical Control and refers to the computer programs which control the machine's operational cycles. Most CNC punch presses are turret-type machines that consist of three basic assemblies: a powered press turret, a main work bed which moves two dimensionally, and a set of controls that include the computer station. The process of punching material involves a work piece, typically a thin metal sheet, being moved into position under the press die along an X- and Y-axis by the computer program. When the work piece is in position, the program instructs the die to move down and form or cut out the desired shape, and then back up to repeat the cycle.

CNC Punch Press
Powered punch presses are large machines typically used in industrial settings to press form or cut out often intricate shapes from thin stock. The CNC punch press is one such machine that is controlled by a computer with very little operator input during the punching cycle. These machines are usually of a turret design that features a hydraulically-powered ram and die set housed in an enclosed turret. A movable table or bed is situated in front of and partially below the turret. This bed can move to feed work pieces along two axial planes, X and Y, or, in other words, backwards and forwards, and side to side.

CNC Punch Press
Both the bed and the die set of the CNC punch press are controlled by a central computer that translates a pre-loaded program into a set of sequential operations for both the die set and work bed. In this way, the machine will automatically advance the work piece through a pre-determined pattern of punch cycles. This automated operation is generally extremely precise and rapid, with typical punch cycles measured in milliseconds allowing for excellent production rates and high levels of accuracy. CNC punching is also economical, as the program can reduce the amount of wastage or scrap generation from any workpiece to a minimum.

CNC Punch Press
The CNC punch press cycle consists of two basic parts — workpiece positioning and the actual punch cycle. The positioning places the workpiece exactly under the die set, and the punch cycle moves the die down to cut out or form the production part. Once the cut or punch is made, the die is moved back up, the work piece is re-positioned, and the cycle is repeated. When cutouts are punched, any scrap produced drops down into a collection bin for recycling. A CNC punch press not only allows for high production rates and outstanding accuracy, but can also generally punch more complex shapes than other press types.

Origin Of CNC Machines

Computerized Numerical Control (CNC) refers to a machine control that is transfigured with the aid of a programmed array of commands distinctively manipulated to execute tasks based on every user.It separates the motion board from the controller board which makes the actual motion board the control via a typical PC. With the utilization of the predetermined instruction,the equipment will then be transfigured to be moving in order to execute specific job.Through this, instructions are established in the medium storage and are converted into codes which will then be compared to the machinery units.

Refreshing the history,the very first NC devices were produced in 1940 s as well as 1950 s. These crude equipments had been then altered and renovated with analog and extremely technical computer programs which paved the way to the development of the current Computerized Numerical Control (CNC).It Is modern units have element patterns which are superiorly computerized and highly systematic with the usage of complex programs such as Computer-aided-design or CAM. These complex commands generate data that will transfigure the instructions that are extremely important in order to control specific machinery.

CNC Milling Machine
Since some of the units of the machine require different equipments,they are frequently altered with tools having the capacity to perform multiple tasks in a single cell. Sometimes,different units associated with instruments are maneuvered by using an external controller.In any circumstance, various process of the directions needed to accomplish tasks is all electrical and can generate an element that is nearly similar to a genuine CAD pattern.With the never-ending evolution of modern tank for data and information,the utilization of paper tapes remains very typical since it renders convenience and ease to every user.Still, anyone discovers it a lot easier to include mp3 reader in a microprocessor controller when compared to added workload when you need to re enter tapes in to another set of pattern.Another stronger way being used is to change from the paper tapes to Mylar tapes.

The fast revolving innovation of CNC machines yielded towards the need of acquiring latest CNC specifications not thwarted by the procedure for licensing specific units and styles. There are different factors to consider in order for it to last a bit longer and majority of them are dependent from vector markup languages.Units if CNC controls obtain commands through G-code that will then be set up to G-code motion,and then the controller will analyze the file with the help of signal pulses which will command the machine for any intriguing movement and execution.

CNC Machine Lathe
Using the development of CNC controller, the commands and features became very easy to operate. Much more,all of the CNC controls enable motion axis to be executed with more basic and logical means.These modern units are proven to be extremely effective and computer-operated with the use of CAM and CAD. Despite the high specialized approach and complex types of the computer files, they are still considered very important in machine operation.There is no doubt that these device units are one the sought-after technology during this time.

Be more concern with the health of your gadgets and resources in your business. You should learn about the basic principles being a responsible designer and how to be productive utilizing CNC controller. It will help you handle your tasks at once. Do not simply let it down and learn to deal with the needs of your business.

How CNC Helps Companies

The advent of Computers lessened the requirement for human intervention in just about all aspects of our daily lives.This is especially true in the industrial sector now that production is virtually automated.

Precision and precision
Computer numerical control has been able to help companies in terms of precision. With the requirement for more complex designs and more complicated operations,human workers could not cope with the required precision that accompany advancement. CNC machines were able to alter which idea by allowing increased precision and lesser error percentages with regards to production.

Another important enhancement that CNC has brought with it is the increased accuracy. The dimensions of components have to be very accurate.As well as since an increase in production speed also increases the error ratio,CNC has helped lower that ratio by the increased level of automation and the error recognition capabilities that computers have.

CNC Machine Lathe
Pace
In the industrial sector,pace is of the essence.With CNC technology,the normal production capacity has been elevated exponentially.This means that effective and accurate production methods have been developed.Mass production requires more scrutiny for mistakes and mistakes.However,anomalies can also be corrected.The encoding structures of CNC machines can be altered in a fast way.This means that mistakes do not have as serious an impact as they had before CNC was improved to this degree.

Machine versatility
CNC machines have become very versatile with regards to the tools that they use.They can easily be assigned to different tasks and thus can be very productive.Tools and systems can be switched without compromising the speed of the production. Aside from this,one machine can do more than one task at a time.This exceeds the normal human capabilities as it allows more tasks to be accomplished at a faster rate compared to before.

Furthermore,when 1 machine tool breaks down,it may easily be pulled off the power grid to prevent it from impacting the whole production cycle.It may then be replaced or repaired on the spot.



CNC Milling Machine
Lesser human treatment
Since component production is a very tedious and repetitive procedure,human error skyrockets as time passes.This is due to fatigue along with other factors.Furthermore, the ability of an individual degrades due to psychological and emotional factors.This means that if a person creates the same job for a certain amount of period,the person may eventually get bored or tired or both.This increases the possibility for the human to commit an error and thus causes a drop within the efficiency rating of that individual.A machine,however,does not get tired or bored.A machine does not have any concern at all.

Therefore,a machine increases efficiency ratings through speeding up production and getting rid of or reducing factors which threaten efficiency.In this case,1 must simply program the equipment to start a cycle.In addition, humans have to be fed,paid,and rested. Machines only have to be rested when failures occur to often and they need not be paid or given.

This brings us to the conclusion that companies will be able to save a lot in the long run. Whilst investing in CNC machines is not cheap,maintenance will only cost a fraction of what will be paid in order to manual laborers.

A Code used in CNC Programming

G Code - A Code used in CNC Programming
G-code is the common name for the most widely used numerical control program language. G-codes are also called as preparatory codes, and are any word in a CNC program that begins with the letter. G-code programming environments have evolved in parallel with those of general programming from the earliest environments like writing a program with a pencil or typing it into a tape puncher to the latest environment that stack CAD,CAM and richly featured G-code editors.

Generally it is a code telling the machine tool what type of action to perform, such as:

G-code command
- Rapid Move

- Controlled feed move in a straight line or arc

- Series of controlled feed moves that would result in a hole being bored,a work piece cut(routed) to a specific dimension,or decorative profile shape added to the edge of a work piece

- Set tool information such as offset

G-code
G-code began as a limited type of language that lacked constructs such as loops,conditional operators,and programmer-declared variables with natural-word-including names (or the expressions in which to use them).It was thus unable to encode logic;it was essentially just a way to connect the dots where many of the dots locations were figured out longhand by the programmer.The latest implementations of G-code include such constructs,creating a language somewhat closer to a high-level programming language.The more a programmer can tell the machine what end result is desired,and leave the intermediate calculations to the machine,the more s/he uses the machine s computational power to full advantage.

Advantages of CNC Machining

CNC machining stands for "computer numerical control" machining. It is a relatively new process in the world of machining which allows for increased efficiency through higher levels of automation and by allowing the machine and it's computer controls to do all the work. While CNC machines are expensive and complicated, they quickly pay for themselves by reducing the workload and preventing errors.

The first major advantage of CNC machining is that it improves automation, removing the need of an operator for all but a few parts of the work. CNC machines can be left unattended for hours or even days if necessary, allowing operators to focus on other tasks. This also allows for a company to retain fewer operators, thereby saving on overhead. By removing the operator, safety is also increased, since should there be a jam or other potentially dangerous machining error, the operator will not be holding the tool and the only thing damaged will be the tool itself. CNC machines can also work much faster than human machinists, since they are faster, stronger, and do not need to take breaks. They can also be run late at night, when most of the workers have gone home, since machines do not need to worry about being sleepy or getting paid overtime.

Advantages of CNC Machining 
The second big advantage to CNC machining is that it produces an exact result every single time. Even the best human operator will have minor variations between finished results, whereas a CNC machine will produce exactly the same result each and every time it is run. This is very important in the modern world of standardized and interchangeable parts, where a single defective cut can make an entire machine wholly unusable. All that is necessary is for a single program to be developed and placed into the machine. Then the machine can toil away at however many work pieces are needed, producing an exact replica down to thousandths of an inch each and every time.



CNC Machining Part
The third big advantage to CNC machining is the flexibility of the machine itself. While humans are much more flexible and trainable than machines, a CNC machine can be completely reprogrammed in a matter of hours to produce a completely different product. It is thus possible to refer back to old programs or install new programs when a different work piece is required. This gives CNC machines a big advantage over other machines, since they can quickly shift to producing a completely different product without the installation of many new parts or a major overhaul of key components. This also ensures that CNC machines can keep up with customer demand, since they can very quickly shift from making a part that is in surplus to a part that is lacking should a need arise.

What is CNC Machine Parts

It's the first text written to fully integrate basic machine tool and CNC concepts throughout. Beginning in the first chapter, the differences between manually-operated and CNC equipment are shown and compared. The text is written for introductory courses, and does not assume previous machining background on the part of readers. Part I discusses the basics of today's integrated manufacturing world. In Part II students learn to safely set up and run manually operated equipment, always with the goal of transferring their skills to CNC systems. Computer is programmed with the use of software tools, like CAD and CAM to create the parts correctly by making the right and accurate movements. As there are a number of CNC machined parts available that are used in these machines, so before getting these parts, you should take the machine into account

CNC Machine Parts
CNC machined parts used in a CNC machine, and are generally used for various purposes such as cutting, routing, milling, drilling or anything that can be operated on materials like wood and metal. These machines are used in manufacturing processes using the automatic procedure from computer to help build forms and shapes which should be accurate. CNC machined parts are used to process raw materials that are put into the machine and cutting tools are used to shape them in various forms. For this process, they need computers that have a number of storage units and run on one or more microprocessors.

CNC Machine Parts
Axis, cutting tools, control panel, coolant supply tube, table and spindle are some of the common CNC machined parts. These CNC processes save a lot of time of the operators and also save a lot of business money because they are automated. The operator can load the material and then program the machine according to the needed work, and the machine will perform the task. The machine will follow the instructions and give out results after running for the given time. Once you set all the work and load the material, your work is completed because the machine will do the rest of the work.



If you want to work fine with CNC machined parts, then it is required to understand the operation of the machine. Apart from knowing the general procedure for running the machine, you must also know the CAM and CAD codes to program it. Since CNC machines work on routing, so you should also know the basic routing procedure.

CNC MACHINING INTRO

CNC machining, short for computer numerical control machines. It means controlling the computer to read the instructions on the company and the drive and machinery products to meet specific requirements. Imagine a robot that can create different products depending on the specific instructions given to it.

CNC machine work this way. It's like a robot that can do things exactly the way you want. CNC machining is the unison between the world of software and the world of production. Department to bring the two together and produce a more efficient and effective as possible. It is unlikely that any time or energy to lose the use of this technology.

CNC machining goes a long way back. Prior to machining, CNC machining with the NC stands for NC machines controlled by a number. This is not the kind of mechanical aid of a computer program and can not be adjusted to suit the needs of suppliers or customers. The products were very straight and rigid during these You are very fortunate now that you have a CNC machining technology at your disposal. With the introduction of CNC machines, things have changed.

CNC machining
CNC machine tools or equipment that are important to the industry. It is used to assist in the design and manufacture of products. These CNC machines are programmable to meet specific needs of users. They can recover and can continue to work without any interference, you can sleep at night and out of the machine that will work for you. To the error detection software has been developed to inform the user if something has gone wrong in any situation.

CNC machines are controlled from a software environment. This is usually a CAM software package or a computer aided manufacturing software package. Through this kind of software, paperwork is reduced. There is no need to put the design on paper. Instead, after the object or product is designed using the software, it is sent straight to manufacturing.
If you’ve heard the term paperless organization then this is one concrete example.

CNC machining allowed manufacturers to do curve cuts as easy as straight cuts. Three dimensional structures were also as easy to build with the introduction of CNC machining into the industry.
Human intervention in the making of products was reduced dramatically. Their intervention on several manufacturing steps have either been reduced or removed completely.

Aside from the ease of use that CNC machining has given its users, the consistency and the quality of the output has also been improved. With this technology, the likelihood of errors has been dramatically reduced. The amount of time spent on rework has been reduced as well. The final output that is produced through this kind of process is done in a very efficient manner.

CNC machining has so many applications and a bright future ahead of it. Only time will tell the blossoming potential of such useful technology.

G-Codes, M-Codes And Do I Have To Be An Expert On Them

What is an M-Code?
M-Codes are related to G-Codes. M-Codes control different machine functions. Some of these functions are turning the machine on and off. Turning the spindle on or off. Turning a plasma torch on or off. Turning coolant on or off. You get the idea. When programming your CNC machine you may need to perform these functions.

Like G-Code, M-Codes vary from manufacturer to manufacturer and from machine to machine. As you can imagine you would need an M-Code for turning a plasma torch on and off on a CNC Plasma Cutting Machine. You wouldn't need an M-Code to turn a spindle on and off though. Hey, the machine doesn't even have a spindle.

Do I need to be a G-Code Expert?

M-codes
In a word, no. You will probably need to know how to quickly scan your G-Code if you are having problems during your machining simulation. Other then that G-Code and a CNC program are throwaway programs for the most part. What do I mean by that? Let me explain.

Let's look at a specific design. Let's say a 12" by 12" square. You build your model, run it through your CAM Software and create a CNC Program made up of G-Code instructions to your machine. Say tomorrow the job requirements change to a 24" by 24" square. Do you go into your G-Code line by line and change the code? Most people wouldn't. They would go back into their CAD or CAM program and scale the square up to 24" by 24". Then post-process the job again to get their G-Code program.

There are some people that would do this line by line because the design is simple. Now think of a complex shape and what scaling it up or down would entail. Massive changes to the G-Code and reviewing it line by line. We are talking thousands of lines here vs. going back and quickly scaling the model and spitting out some new G-Code. And that is why G-Code is throwaway. Use it over and over when you can, but don't fret over archiving it if something changes. It is much better to make a copy of the design (CAD File) in its original state and save that somewhere. That is much more useful.

CNC - G codes




Post Processing - Ok, you have me worried. With all the variations in G-Codes and M-Codes, how will I ever keep it straight?

Don't worry about that. The CAM program you choose will have many Post Processors. Post Processors are like translators. They help the CAM Program spit out the right G-Codes for your specific machine. All you have to do is select the right Post Processor before you spit out the G-Code. That is simple.

Most CAM programs have many machine specific post processors already loaded. All you do is to the list of them and click on your machine to select it. If you build your own machine, there are generic post processors loaded for different types of machines. Usually you pick a generic one and modify it a bit with a little testing. You are making sure a move in the X-Axis positive direction really means what you want it to mean.

How to Set up a Cnc Milling Machine

There are many factors that have to be addressed before this question can be properly answered. Is the machine a vertical machine or horizontal machine? How any axes will be required? What is the capacity of the tool turret? How are you planning on holding the part? Assuming the programmer has answered these questions for you, lets proceed. Although every CNC milling machine set up will be slightly different, these are the generic steps I follow on a daily basis for a 3 axis vertical CNC milling machine.Note: I am assuming you know some basic machining practices. For example, how to use an edge finder, how to navigate through your machine's control, and knowledge of basic CNC control commands

Set up cnc Milling Machine
Steps:
1. Clean all surfaces, for example table, vise jaws, part very good with a lint free cloth.

2. Load tools needed. (including edge finder)

3. Load part in vise or how ever your work holding is going to be.

4. Set work fixture offsets. Make sure the machine is using the WFO that the program will be using. If not, switch to MDI mode, type in G54, or G55, or G54.1P15, what ever the program will be using. Hit Cycle Start. Using an edge finder, pick up the X0. position the programmer had previously established. Go to your WFO page and add the machines absolute X value to the value currently in the WFO's X registry. Do the same for the Y axis.

5. Set the tool length offset for each tool by loading first tool in spindle. Manually move the Z axis down until the tool's tip is near the Z0. position the programmer had previously established. Get a piece of 0.001" shim stock and hold it between the part and the tip of the tool. Carefully and lower the Z axis in 0.0001" increments until the shim stock an be pulled with a slight drag. Go to your tool length offset page and enter the machine's absolute Z value plus -0.001 in the tools registry. Repeat procedure to additional tools. Note: -0.001 is added for the shim stock's thickness.

6. Enter any diameter offsets that may need to be entered if tool radius compensation will be used in the tool offset page.

7. Adjust coolant lines so coolant can properly cool tools and wash chips away.

8. Put machine in slow rapid, Single Block and then press Cycle Start. Be careful and read every block programmed and watch each movement the machine makes ready to stop the machine in case there are any programming errors. (You could also run the program 5" or whatever above the part to make sure every thing is good and use Dry Run if you feel it necessary.)

CNC Knowledge Levels

There are a variety of different levels of knowledge and skill with CNC. You need to figure out where you fit in to the topic. When you know your level, your learning on the subject will be much more effective.

If you are an expert in a subject, you can blow through most subject areas and only pick up what you need. You can readily see the new ideas proposed because you know the lay of the land. If you are a newbie, take your time and study intently. Then go back and re-read the topics again and again. With each new read you will be able to pick up more and more. This is very similar to the proverb, "the teacher will appear when the student is ready."

CNC Knowledge level
CNC Knowledge Levels:
CNC Newbie:
Hobbyist or student
You need to learn the general process of CNC
You have heard various CNC terms, but don't know what they mean or how they relate
You might have some end result idea of what you want to do with CNC

CNC Beginner:
You probably know the general process of CNC
You stumble across problems with programs or the machine on a regular basis
You have some learning "battle scars" and could maybe explain some basics to others

CNC Intermediate:
You know the process of CNC and have worked through it multiple times
You can see and recognize problems before you ever begin machining
You understand the software you use and all its nuances
You have machined multiple parts out of multiple materials.

CNC Advanced:
You know what "Fanuc, Mazak, Canned Cycles and Conversational Programming" mean
You probably work in a production environment with CNC technology every day
This book is probably not for you

Take a minute to score yourself before we move on. It will be valuable for you to know what level you are at and what level you are headed to next.

As a generalization this book was written for the Newbie to Intermediate CNC students. Everyone who works with CNC can probably learn a thing or two, but Advanced CNC users probably know most of these concepts like the back of their hands.



One last note before we get going:
From time to time I will get an email from an expert telling me this or that is not perfectly, technically correct. Usually I agree with them. What I have tried to present is how I learned CNC and how I made this stuff work in my mind. Think of it as a Layman's Guide to CNC vs. a PHD Doctoral Thesis with years of Data Collection and Analysis on the topic. My point is always to teach, not gain recognition in scholarly journals.

Milling Manufacturing

Milling is the process of cutting the feed of a workpiece in a rotating knife several teeth. The cut of the many actions around the teeth Mills offers a fast method of processing. The machined surface may be flat, inclined or curved. The surface can also be made to any combination of shapes. The machinery for the execution of the piece, the rotating blades and is known to feed milling machine

TYPE OF MILLING

Face milling
In face milling, the cutter on an axis with a rotation axis mounted vertically on the surface of the piece. The ground surface away from the action of cutting edges on the periphery and in the face of the cutter.

Face Milling
Peripheral Milling
In the peripheral (or plate) of milling, the milled surface of the teeth on the periphery of the cutter body has been generated. The axis of rotation of the cutter is usually processed in parallel on a flat surface of the workpiece.

Peripheral Milling
End milling
The milling cutting turns on an axis perpendicular to the general, the work piece. Can be tilted to machine tapered surfaces. The cutting teeth are on the front of the cutter and the periphery of the cutter body is found.

How to Lathe operations?

The wheel, of course, is based around. Besides making several transactions can be performed on a lathe.
Boring : Boring is always the extension of an existing hole, possibly through an exercise can be done or the result of a core in one piece. Equally important and at the same time, the objective can be boring, make the hole concentric with the axis of rotation of the workpiece and thus no eccentricity, correct abortions performed with the drill from the midline. The rotation is an important attribute of the holes. If it's boring made on a lathe, generally, the work is done on a plate or in a front panel. Holes can be drilled, straight, tapered or irregular contours. Boredom is essentially boring, while feeding the tool parallel to the axis of rotation of the workpiece.

Lathe operations
Facing : Compared to produce a flat surface as a result of a tool is fed through the end of the piece in rotation. Unless the employment is maintained on a mandrel, must be overcome if both ends of the work should be turned end for end after the final closed first and before repeating the operation. The cutting speed should be determined by the largest diameter of the surface facing. Front can be performed either from outside to inside or from inside to outside. In any case, the number of the tool is placed exactly at the center of rotation. because the cutting force tends to push the tool away from work, it is usually necessary to prevent the car around the bed when you look at IDC's technology to avoid slipping and so light a surface that is not producing planes. In the wake of pig iron or other materials that have a hard surface, which should be sufficient depth of the first cut in order to penetrate the hard material to prevent excessive wear of the tool.

Parting : Parting is the process by which a portion of a workpiece from the rest by a cut of the cutting tool. Since the cutting tools are very thin and has considerable slope, this process is not as precise and difficult. The tool should be clearly defined at the height of the axis of rotation should be kept sharp, have adequate space angles and used in the workpiece in a proper and uniform feeding.

Threading : Lathe, if the first method for cutting the threads of the machines. Although most of the threads are now produced by other methods, turning machines remains the most versatile and fundamentally simple method. Therefore, they often can cut the strings on specific parts, where no configuration or standard size used less expensive methods. There are two basic requirements for thread cutting. One is in the form accurately and correctly mounted thread cutting tool is necessary as a way of reducing the transaction. The resulting thread profile is relatively determined by the shape of the tool and its position in the workpiece. The second condition is that the tool in the longitudinal direction to advance a particular relationship with the rotation of the workpiece should be, because it determines the direction of the thread. This requirement is met through the use of thread and party unity, the positive movement for transportation in connection with the rotation axis.

What is turning machine?

As results from the operation, the machining of cylindrical parts. In its simplest form can be defined as the transformation of an outer surface :

- With a single point cutting tool and
-With the cutting tool parallel to the axis of the feed workpiece distance, the outer surface of the work.

Taper turning is almost the same except that the path is cut at an angle with the axis of the work. It is also the transformation of contour, the distance between the knife shaft work varied to produce the desired shape.

Turning Machine
Even if you do not specify a single point tool, it does not exclude it, multiple configurations of the tool, which are often used in rotation. In the settings, each tool operates independently as a single point cutter.

Factors adjustable cutting force in the transformation of

The three most important factors in a basic turning operation are speed, feed and depth of cut. Other factors such as type of material and type of tool is a great influence, of course, but these three are the ones who can change the operator by adjusting the controls right on the machine.



The speed, always refers to the axis and the workpiece. If it is in revolutions per minute (rpm), tells the specified speed. But the important number for a transaction of money mentioned, the surface velocity or speed with which material workpeece moving beyond the cutting tool. It is simply the product of the speed the size (in feet) of the piece before you start cutting. It is at the feet of the surface engineering per minute (SFPM), expressed, and refers only to the workpiece. Any other diameters on a workpiece cutting speed will have a different, but the rate remains the same.

RSS, always refers to the cutting tool, and is the pace at which the tool along the cutting path. Most Power-FED lathes, the feed rate is directly related to spindle speed and is in inches (the tool in advance) by revolution (the root) or intellectual property rights, he said. The figure, of course, usually much less than an inch and is displayed as a decimal value.

Depth of cut is virtually self-explanatory. Is the thickness of the layer against the workpiece or the distance from the uncut surface of the work away from the cutting surface, expressed in inches. Importantly, however, that the diameter of the workpiece by a smaller reduction than twice the depth, since this layer is removed from both sides of the work.

NC Machine Method

These methods are known as a procedure for NC. The program is part of the machining process competently and also has the program was designed for the numerical control. It is the position of his to plan the sequence of steps that are performed for the treatment of NC, and recorded in a special format.

There are two ways to program the CNC control

- Manual Part Programming
- Computer Aided Programming

NC Machine
With manual programming, the instructions for editing a document prepared as a manuscript of the part program. Basically, the manuscripts, a list of Whiting cutting tool and the positions of the workpiece should be the order followed by the machine to the workpiece. A paper tape was prepared directly from the script programmers.

The last step in the process of NC is on the tape of NC in the use of production. This includes the appointment of raw materials, job reporting and the preparation of tools and devices that require special equipment needed, and the NC machine tool for the job. The machine tool operator function during production of the rough part is loaded into the machine and create the initial position of the cutting tool with respect to the workpiece. The NC machine then takes over the controls and the rest of the operation. When the process completes, the operation that removed part of the machine and load the new part.

Definition of coordinate systems and vectors
Coordinate system and the movements of the machine
For the programmers, the sequence of postures and movements of the plan of cutting tool with respect to the workpiece, it needs to be specified to create a standard systemby axis relative position. With a mock NC as an example, the drilling shaft is fixed in an upright position and the table moves and controlled in terms of spiindle. However, to make things easier for the programmer, we take the view that the piece is stationary, while the drill is moving towards him. According to the coordinate system of axes has been established with respect to the machine table. Two axes are defined as shown in Fig.

CNC Vertical

Milling machines are machine tools which are used to machine solid materials. There are two basic types of these machines and they are vertical milling machine and horizontal milling machine. The two different types are referred to horizontal and vertical because of the orientation of the main spindle. Milling machines can vary in size from small bench mounted machines to much larger room sized machines. Milling machines operate by moving the workpiece around and against the cutter, and the sides of the cutter are used to cut material as well as the tip. The workpiece and cutter are very precisely controlled to thousandths of an inch ( 0.001 ). Milling machines may be mechanically automated, manually operated or computer numerically controlled ( CNC ). The manual operation of some types of precision engineering machine such as the lathe or milling machine are very often controlled by computer or numerically controlled.

CNC Vertical Milling Machine
Numerical control or NC, or computer numerical control CNC refers to the automation of machine tools which are operated by programmed commands that are encoded on a storage medium.

Milling is a machining operation in which a workpiece is given the desired shape by the action of a rotating cutter, while the workpiece performs linear movements. In its simplest form the milling cutter is a circular disc whose rim is provided with specially shaped teeth (cutting edges). The cutters are of many different kinds and shapes. The work is fed against the teeth of the cutter, while the feed motion is longitudinal, transverse or vertical, depending on the type of milling machine and the nature of the work. Milling machines are of the horizontal or vertical type.



Today many CNC milling machines are computer controlled vertical mills, and have the ability to move the spindle vertically along the Z axis. In CNC milling and turning, end to end component design is automated using CAD/CAM programs. The program is put into the lathe or milling machine and the machine is then ready for production. Some machined components will generally require a number of different tooling applications such as drilling, reaming and tapping etc, and most modern machines will combine tools within a single cell. This cell will move or rotate to apply the required tooling application, and this will also be controlled by the CNC system. With todays modern and complex machines, the machined part or workpiece can be moved from machine to machine automatically with the use of computer controlled robots, or human intervention, but in either case the steps needed to produce any part is highly automated and the finished part will closely match the CAD design.

CNC machines were first built in the 1940s and were programmed by using paper tape with holes punched into it at specific points. These early systems were soon overtaken with the augmentation of analogue and digital computers. There is a range of CNC systems that can be fitted to previously manually operate machine tools, and these systems provide a selection of features which can significantly improve the productivity of the machine and the quality of the work that is produced.

3 Axis cnc Milling

In this striving economy, manufacturers are consistently looking for productive ways to complete their parts production operations – the most common way is through CNC milling machines, which are mainly used in performing cutting and drilling operations. Since these machines have succeeded traditional milling methods, it is capable of fabricating components precisely which is important in boosting profitability of one’s business.

Here are a few advantages of this particular CNC machining center that every user should know:

3 Axis CNC Milling Machine
Advantage 1: Such machining center is specifically designed to performed specific milling tasks – Basically, there are several types of CNC milling machining centers, which are horizontal and vertical milling machines. It refers to the positioning of the cutting tool – whether it perform milling operations horizontally or vertically. Other than that, larger size machines are designed to machine larger components and smaller ones vice versa.

Advantage 2: It is capable to fabricate wide spectrum of components – In most factories (or in job shops), there are several CNC milling machines that are used to fabricate components including 3-axis, 4-axis and 5-axis machining centers. Generally, a machine which has higher number of axes can perform detailed and precise cutting operations better than those which have lower number of axes. Therefore, 5-axis machining center can perform fast and precise milling operations far better than 4-axis machining center.

Advantage 3: Most of these machines are controlled by integrated control software – Like any other softwares, it has occasional updates (or improved versions) in order to improve the high precision machine performance on a long term basis. Therefore, machine operator need to be proficient in G-code programming and other conversational programming before they start operating the machine. Nowadays, it common to see machines which are controlled by advanced control softwares, which provides touch screen features and friendlier user interface.

Advantage 4: It is easy to track the progress of the components produced – When the components produced are not within the precision range, you can possibly modify the data or variables that you have inputted earlier, with the intention of improving the precision cutting process. Furthermore, most CNC machine tools have chip management system to reduce unnecessary wastage.

Advantage 5: It has safer milling operations than non-CNC machining centers – In most CNC milling machines, the cutting and drilling operations are carried out within enclosed area. Thus, operators are not directly exposed to the cutting tools as they are distantly using the integrated software control which is located far from the work cube.

By realizing the advantages of a CNC milling machine, it is time that you should consider having it for your business. It is definitely the best investment in improving the productivity of fabricating specific components as well as increases your business revenue.

Steps For Programming the CNC Lathe

Programming CNC turning, you must first have a blueprint of what you need to create After study of the blueprint to do this, you can start programming the appropriate cutting tools for each part by writing a program that states that every move is based on the coordinate system to move equipment into 2. different direction. You must be sure that the tool correctly for them to move correctly and to prevent the hit, as well as core material.

Set the drive as well as information on-screen tools. Information to allow the computer to know what tools, to the position and what the way they will turn the cut material. You also need to introduce the tool to the place that you enter through the end of the tool every day and the location of the machine.



CNC Programing
Specific types of materials and equipment to cut most of the round that you will use for the process of turning. Software uses the rules defined for the feeds and speeds of vehicles using the drive. Aluminium demand faster feeds and speeds when compared to steel, so it is important to have knowledge of the setting material in a way that is correct from the beginning of the program.

A set of commands to the tool to clean the facing material that gives you a point for a consistent starting power. Material is cut, usually metal or band saw, the surface is often rough. But because of the added line turned to a program, your computer will result from the cleaning surface.

The programming process of external rotation, it will cause a cut to the size of the outer end. It can be implemented in two through the use of a bit rough and it will be a tool for changing the dressing tool for the production of clean surface.

To be able to fit the boring bar to the center of the piece, you will need to take advantage of the first set of drilling materials, cut them away to be able to fit in with my stick. Cut out using a glove. This command is useful when more parts of the length of the material. When you are finished pieces, cutting programs and cutting some of the round to be completed and then again it still works automatically set to begin a new dimension.

Type of cutter

Type of Cutter (CNC Machining Process

Slot Drill

Typically this cutter has less cutting surfaces than the two above, and unlike the end mill and ripper can be used to plunge directly into the workpiece. As a result of the reduction in cutting surfaces there is better swarf removal meaning the tool can be used in enclosed pockets and slots.




Slot Drill
Ripper Cutter
Used for the rapid removal of large amounts of metal, the serations along the cutting edge literally rip the material away. This cutter is designed to cut along it's sides only.
Ripper Cutter
End Mill
Similar to a ripper only without the serations, used for removing the bulk of the material. The cutting edges, like the ripper, are down the sides of the tool.
End Mill
Ball Nosed Slot Drill
This cutter, as its name suggests, has a semi-circular cutting face, with the aid of computer software it is possible to cut tangentially to the work piece enabling curved surfaces to be machined.

CNC Drilling

CNC drilling is the way most computer stores the unique short CNC stands for Computer Numerical Control and it is something that represents phase Computer hackers have been working to bring the individual or individuals in some cases many more times longer to perform. Raw pieces are placed in a jig and form a work area before drilling program to be recorded in the computer to start the drilling process as part of a predefined position.

The CNC drilling will help reduce the incidence of errors in the success of the minuscule level. In many cases the margin of error is less than thousandths of an inch. This makes the project come out the same time after time. Drilling can be programmed to place well at the specific as well as to choose the depth that varies for each point in the specimen gearhead will be used if the project calls for a model with a number of holes to drill with. different sizes and depths. Attachment to drill will help to hold several different size drill bits - and the computer tells gearhead to spin himself in the right position to reach a specific point in the material.



CNC Drilling
This will bring mass production to the point where many pieces as if it turned out at the time of consistent and faster than workers could work piece by hand. Position of the point to break a blueprint that specifies the precision; No need to measure again and again to get different results. Drilling does not comply with the final work out correctly the first time.

When the drilling program will be set up to run the press itself. Place a piece of the work of the drilling jig is to choose a program to use, it will see the drilling work. Maintenance drill bit to get them sharp enough to operate without burs out too much or cause a bit to the middle of news stories that people will stay in charge of managing.

Our daily lives have been made to make it easier to advances in computer technology. But most of us are completely aware that computers are not much help for production environments hands-free If no progress of the drilling machine such as numeric computer, our production is very expensive enterprise. The products we buy every day are more expensive because we will need more people to work on these computers will give us a regular basis. Add to this the fact that their products work with your computer every time set.

CNC Drilling Machine

Computer Numerical Control (CNC) Drilling is used for mass production. The drilling machine is multi-function machining center that also mills and sometimes turns. The largest time sink for CNC drilling is with tool changes, so for speed, variation of hole diameters should be minimized. The fastest machines for drilling varying whole sizes have multiple spindles in turrets with drills of varying diameters already mounted for drilling. For turret lathe no need to remove drill.

Many types of semi-automated drilling machines are also used. An example is a simple drill press which, on command, drills a hole of a set depth into a part set up beneath it.

CNC Drilling Machine
In order to be cost-effective, the appropriate type of CNC drilling machine needs to be applied to specified part geometry. For low-volume jobs, manual or semi-automated drilling may suffice. For hole patterns with large differences in sizes and high volume, a geared head is most appropriate. If holes are close to each other and high throughput is desired, a gearless head can locate spindles close together so that the hole pattern can be completed in one pass.

What is CNC Punching

Steel products are all from the car to your computer for grilling. The process to create a hole in the steel design to accommodate almost any metal can be related to how many completely different.

One method is called the "Milling" and in some cases, "machining" will slow down the hole in the ground by drilling steel with no difference in performance over mobile penetration only at much larger.

How to quickly create a hole in the metal known as "stamping" associated with known punch press. Punch press can quickly use the ten and twenty and fifty or five hundred tons. (Or more) of pressure to the floor of the steel press system Punch - and - death by the "punch" as the elements that protrude and "death" is a plane that has space for elements recessed outreach to seal. Elements that protrude (Usually on top) smashes into steel (such as "drilling" or "stamp" steel) with several tons of pressure I slapped the steel called shot, which usually fall into recession over die entire process. less than a second and complete metal, usually as a result. This process pump is by far the fastest way to bring a metal hole. Often very costly to create and install die punch for punch press, even the return of the system ie, the cost per piece is significantly less than the method otherwise after the installation has been created.

CNC Punching
While a stamping operation is ideal for high production work for some time million pieces do not have to work and it is not possible or logical. If you do not have high productivity, it is often difficult to justify the cost of installing pumps.

When the cost of making a stamping operation is not justifiable, the buyer can not reasonably open to a process called CNC drilling. While the strike has been designed for high production of ten thousand or more parts, CNC drilling is designed to increase the effectiveness of short-term costs associated with the amount of ten thousand pieces or less. CNC drilling is by far the fastest way to import steel hole without having to pay in advance for the fight and installation of pump died.

The word "CNC" refers to the "Computer Numerical Control", a system of using computer technology to manage effectively in a format that is very clear. In the case of CNC drilling, computer code is used to order the pump. (Similar to a punch press) to drill a hole steel While pressing, stamping can participate in the hit single, hit the drilling CNC is a part along with the hits - quickly usually storage device or drive turret feed punch and accurate. Death became the center of the punching machine. Then the machine was ordered to clear from your computer to drill one hole in a position determined by a computer program several CNC drilling machine to drill a hole in half a second or less. While a time-consuming part is not necessary to wait for the punch and die system is expensive to do.

Milling is used in case of only two or less (master) or design defects, or unsuitable for heavy metal scavenging Hammer used in cases with multiple parts to be made CNC drilling in the value of the middle part. The method you choose often depends on the number of parts that you need.
