CNC Milling is a machining process which employs rotating multi-point cutting tools to remove material from workpiece. CNC mills are capable of running on programs comprise of number-and letter-based prompts that guide pieces acorss various distances. The programming employed for a mill machine could be based on either Gode or some unique language developed bring team, Basic m-cos consist of a three-axis system (X, Y and Z), though most newer mills can accommodate three additional axes. Operitional capabilities of the milling process include face milling-cutting shallow, flat surfaces and flat-bottomed cavitites into the workpiece-and peripheral milling-cutting deep cavities, such as slots and threads, into workpiece.
