CNC Machining of Ferrous and Non-Ferrous Metals

CNC machining refers to the machining process proceed by Computerized Numberical Control (CNC for short). It is aided by the CNC to reach a high and steady accuracy with less labor cost. Machining is any of various processes in which a piece of raw material is cut into a desired final shape and size by a controlled material-removal process.

The processes that have this common theme, controlled material removal, are today collectively known as subtractive manufacturing, in distinction from processes of controlled material addition, which are known as additive manufacturing. For some of the applications, just castings or forgings without machining could reach the desired tolerances and surface requirements. However, for most situation, the CNC machining are needed to match the customer's unique specifications and to make sure that the finished metal parts could work properly with other parts. Even for the investment casting parts, which have much better surface and tolerance grade than other metal forming process, still need additional processing.

To ensure the high quality and precision of the finished machining parts, the computer programs is critical. The Computer Aided Design, which is called CAD for short, and Computer Aided Manufacturing, called CAM, are both used as programs to provide detailed instructions about each step of the precision machining process. Programs like SolidWorks, ProE and UG create extremely detailed 3D models.
