GB/T 39128-2020Numerical control system of machine tool—Human-machine interface (English PDF)

3.1 Machine CNC System

A control system that uses numerical control to control machine tool processing functions.

Note 1.Machine tool numerical control systems generally include hardware devices and corresponding software. The machine tool numerical control system is mainly composed of a numerical control device (also called a control unit) and a driving device (Motor drive unit and motor, sensor) and other components. The numerical control device is the main part of the machine tool numerical control system, which mainly includes a microprocessor, a

Hardware (and/or circuits) such as moving (position) controllers, memory, input/output (I/O) and communication interfaces, man-machine interface (display and keyboard), operating buttons (keys), etc.

And the corresponding control software.

Note 2.There are multiple classification methods for machine tool numerical control systems. According to different functions, machine tool CNC systems are usually divided into three types. simple type, high-performance type and popular type;

According to the different application technology, it can be divided into two kinds of special and general CNC systems; according to the different feedback control forms, it can be divided into open loop control and semi-closed loop control.

There are three types of control and closed-loop control; according to the different processing control methods, it can be divided into three types. point control, linear control and contour control.

Note 3.Rewrite JB/T 11989-2014, definition 2.1.3.

3.2 HMI

Information between the machine tool numerical control system and external operating entities (such as the operator through the network, other information processing equipment and control devices)

The interactive medium is composed of hardware man-machine interface and software man-machine interface.

Note. Rewrite GB/T 18759.1-2002, definition 4.3.2.

3.2.1 Hardware man-machine interface

Hardware equipment for users to modify and set internal software operation process and data.

Note. It mainly includes the control panel of the numerical control device.
