CNC milling is a process where a workpiece is machined using computer-controlled equipment. A variety of bits and tools are often used to cut, grind, cut, polish and otherwise form shapes inside the three-dimensional workspace of the machine
The term ※CNC§ stands for Computer Numerically Controlled. It refers to any device that can be programmed to perform a specific function by means of computers and numerical control (NC) systems. An example of this would be using a CNC milling machine to cut metal parts into intricate shapes, such as gears or other mechanical components. Another common use for CNC mills is engraving artwork onto plastics or metals
There are two types of CNC machines: manual and automatic. Manual machines are manually operated by an operator who moves the tool over the workpiece in order to cut, grind or shape it according to their design specifications. Automatic machines are also manually operated but instead rely on computerized controls that allow them to perform different functions automatically without human interaction or effort on behalf of the operator.
