1. NC

is the abbreviation of numerical control. Digital control, referred to as numerical control. It refers to using discrete digital information to control the operation of machinery and other devices, which can only be programmed by the operator himself

The early numerical control system is composed of hardware circuit, which is called hardware numerical control (hard NC). After 1970s, the hardware circuit components are graally replaced by special computer, which is called computer numerical control system. Generally, special computer is used and equipped with interface circuit, which can realize the action control of multiple numerical control equipment. Therefore, the current CNC is generally CNC (computer numerical control), rarely use the concept of NC

2, MC

is the abbreviation of micro computer, the microcomputer in index control

There are three levels of microcomputer system from global to local: microcomputer system, microcomputer and CPU. A simple microprocessor and a simple microcomputer can not work independently. Only a microcomputer system is a complete information processing system and has practical significance

3, ATC

is the abbreviation of automatic train control

the system includes three subsystems: ATP automatic train protection, ATO automatic train operation and ATS automatic train supervision

extended data:

computer numerical control is also known as numerical control. To understand computer numerical control, we should begin with understanding numerical control

Numerical control is the abbreviation of digital control. Numerical control technology is a method of using digital information to control mechanical movement and machining process

in the early days, there were two versions:

NC (numerical control): representing the old and original numerical control technology

CNC (computerized numerical control): computer numerical control technology -- new version, the preferred abbreviation of numerical control

NC may be CNC, but CNC does not refer to the old CNC technology

NC usually controls mechanical quantities such as position, angle, speed and switching quantity related to mechanical energy flow direction. The generation of numerical control depends on the appearance of data carrier and binary data operation
