CNC Milling Machines are machine operated cutting tools that are programmed and managed by Computer Numerical Control (CNC) systems to accurately remove materials from a workpiece. The end result of the machining process is a specific part or product that is created using a Computer Aided Design (CAD) software.
Noted: there are 3 axis, (3+1) or 4 axis, (3+2) or 5 axis cnc milling machine, and the most popular is 3 axis machine which can machine most of parts.
Operation types of CNC Milling Machine
During the cnc milling processes, a variety of operations may be performed to the workpiece to yield the desired part shape. The following types of operations are each defined by the type of cutter used and the path of that cutter to remove material from the workpiece for a cnc milling machine.
