Engineering Degree Program in China - Numerical Control

1. Introduction

Numerical Control is the process that uses the method of computer programs to control the machine, to conduct processing on mechanical parts according to the procedures edited by the staff in advance. Numerical control is the technology that uses digital control to realize the automatic control of a certain working process. It is usually controlled by the position, angle, speed and other mechanical parameters and the switching value related to the mechanical energy flow. The emergence of the numerical control is dependent on the data carrier and the binary form data operation.
