About CNC MachiningCNC stands for Computer Numerical Control. CNC machining is a modern machine processing that entails computer controlled machines that perform a wide variety of functions. In metal fabrication, CNC machining involves the use of computer driven machinery to perform such tasks as metal cutting, metal welding, shaping of the metal components and finishing the components. The original metal fabrication machines were initially called numeric controlled (NC) and they were invented in the late 1950s by John T. Parsons in conjunction with MIT University. The machines used G-Codes that gave the machines 'go' instructions. The G-Codes defined the positions of the machines and they instructed machines to perform specific functions. The machines were built for a specific function and it was quite hard changing the functionality of the machine. However, in 1970s, computers were incorporated into the machines to allow for different programs to be applied to a machine. This means that with a change of the controlling software, the machines can be reprogrammed to perform different functions. Today, CNC machining uses computer aided design (CAD) and computer aided machine (CAM) technology to execute their functions. Types of CNC machining tools CNC machining for milling are used to cut various materials including plastics, metals and wood. They use G-codes program to define the processes of cutting, the depth of cuts and the various designs of cuts in the various materials. However, there are other milling machines that use propriety software as opposed to G-Codes to run the machines. Either way, the propriety software are intuitive and similar to G-Codes and operators can easily switch from one program to another. CNC machining for grinding are machines that use a grinder to mold metal to the desired shape. The process is computerized and the machine is able to achieve various metal forms with precision and speed. CNC machining for lathes is the process of using computer controlled equipment to cut through material using lathes. The machine controls for speed and accuracy while cutting metal pieces. It achieves materials and finishes that are not possible with the former manual method of lathing. By automating processes by use of a computer, the various machining processes are achieved with greater precision and accuracy. This allows high quality, produces less waste and faster production production. The CNC machining allow for 3D machining with the aid of robots and other sophisticated equipment. CNC machine shops are able to produce large orders in a short time. Where to get CNC Machining services There are various places you can get CNC machining services. These services are available through CNC machining shops. The shops enable customized fabrication of material, development of prototypes, and various other manufacturing processes.
