What is CNC Machine
CNC machines are making parts around the world for almost every industry. They create things out of plastics, metals, aluminum, wood and many other hard materials. The word “CNC” stands for Computer Numerical Control, but today everyone calls it CNC. So, how do you define a CNC machine? All automated motion control machines have three primary components – a command function, a drive/motion system, and feedback system. CNC machining is the process of using a computer-driven machine tool to produce a part out of solid material in a different shape
The CNC depends on digital instructions usually made on Computer Aided Manufacturing (CAM) or Computer Aided Design (CAD) software like SolidWorks or MasterCAM. The software writes G-code that the controller on the CNC machine can read. The computer program on the controller interprets the design and moves cutting tools and/or the workpiece on multiple axes to cut the desired shape from the workpiece. The automated cutting process is much faster and more accurate than a manual movement of tools and workpieces which is done with levers and gears on older equipment. Modern-day CNC machines hold multiple tools and make many types of cuts. The number of planes of movement (axes) and the number and types of tools that the machine can access automatically during the machining process determine how complex a workpiece a CNC can make.
