Introduction to Machining Processes

Machining Process
Machining, by definition, is the process of removing materials from excess and unwanted stock by use of machine tools and converting them into usable parts. Different processes like turning, milling, drilling and grinding are used to remove and modify a metal or a plastic into a machine usable part.Machines have brought a revolution in the industrial world in the last few decades. Earlier, people used to manually extract metals and transform them. But, with the entry of machines in the industry and the invention of first steam engine by James Watt, the whole scenario changed. Today, machines are used in different industries for multiple purposes. The upcoming technology and software have also added to the use of machines. Internet has added to the usefulness especially to machining services and availability of spares via the virtual world.

Machining Process
All the manufacturing industries use variety of machines to meet specific manufacturing requirements and choose the right machining vehicles. Those manufacturing machines comprise of diverse materials like aluminum, steel, stainless steel, copper, polycarbonate, plastic, fiberglass and acrylic among others. To achieve a perfect and finished piece of material, different methods are applied on the piece depending on its final usage. Most commonly used methods for removing and modifying a raw piece are blending, blanking, boring, drawing, polishing, anodizing, grinding, honing, knurling, laser cutting, milling, plasma cutting, reaming, welding, thermoforming, gear cutting, shearing, sawing and the list goes on.. These methods are responsible for providing dimensional accuracy and perfect surface finish to a particular piece of metal.

Machining has various advantages. The process has resulted in greatest efficiency, low cost production and faster delivery. It also gives room to manufacture extensive pieces with more design flexibility, closer tolerance and consistent component properties. Lower residual component stresses and faster turn around time are also the major benefits of machining. Machining as a process is widely used in large industries for producing an extensive and outstanding piece. The process is used in industries like transportation, construction, packaging, electrical, automotive, aircraft, hospitals and medical applications among various others. There are exclusive sites that promote machining solutions and functions as an excellent CNC machine shop.

An online manufacturing machine shop allows customers to generate their own manufacturing products using custom parts provided by the online machine shop. Clients also have an access to download various user manuals, help guides and CAD software that can help them design various objects. It is a global gateway to enter into a world of innovative machinery.
