The earliest numerical control machines date to the 1940s when motors were first employed to control the movement of pre-existing tools. As technologies advanced, the mechanisms were enhanced with analog computers, and ultimately with digital computers, which led to the rise of CNC vowin.cn/en/News/news1251.html' target='_blank'>machining.

The vast majority of today’s CNC arsenals are completely electronic. Some of the more common CNC-operated processes include ultrasonic welding, hole-punching and laser cutting. The most frequently used machines in CNC systems include the following:

1.CNC Mills

2.Lathes

3.Plasma Cutters

4.Electric Discharge Machines

5.Water Jet Cutters
