CNC milling is a machining process used to produce designed prismatic parts. When the CNC milling machine works, milling tools with rotating cylindrical heads and a plurality of chip grooves are usually called end milling cutter or vertical milling cutter, which can move along different axes and be used to machine long and narrow air, groove, external contour, etc. The machines used for milling are called milling machines, CNC milling machine is usually an Computer Numerical Control (CNC) machining center. Milling includes manual milling and CNC milling, which are carried out in the machining workshops.
