CNC milling is a machining process that utilizes computerized controls to manage the movement and operation of multi-point rotary cutting tools. As the tools rotate and move across the surface of the workpiece, they slowly remove excess material to achieve the desired shape and size.
The CNC milling process can be broken up into four distinct stages:
>CAD model design: engineers create a 2D or 3D design of the desired part
>CAD model conversion to a CNC program: the design is exported into a compatible file format and converted into machine instructions using CAM software
>CNC milling machine setup: the machine operator prepares the machine and workpiece
>Milling operation execution: the machine operator initiates the machining program
