Problems solved by technology

Although this solves the real-time control of mechanical equipment, the peripheral circuit is complex and needs to rely on the operation panel as the interface for man-machine exchange. There are usually a large number of hardware devices such as operation buttons, switches and indicator lights, and the operator needs to input more complicated Instructions are cumbersome to operate, and the performance of hardware devices is not good, the failure rate is high, the stability of the system is poor, the maintenance workload is heavy, the fault point is difficult to find, and maintenance is inconvenient

Embodiment Construction

[0043] Referring to FIG. 1 : the present invention includes three parts: a touch screen 10 , a PLC programmable controller 20 , and a machine tool servo system 30 .

[0044] The touch screen 10 is a window for the user to conduct man-machine dialogue. All the operation interfaces are designed by the programmers themselves. It has functions such as machine tool operation, status display, data follow-up, data storage and calculation. Its specific control part mainly includes function selection module 1, data input module 2 (keyboard), data calculation module 3 (CPU), data storage module 4, data following module 5, switch control module 6, state monitoring module 7; Wherein, except Except the data calculation module 3 (CPU) and the data storage module 4 are hardware, all the others are software.

[0045]In the way of programming configuration, first make the function selection module 1, the user can freely switch the operation interface to meet the control of different axes. Mak...

Abstract

The invention relates to a control system and method of the digital control machine which is characterized in that it uses the contact screen to displace the CNC, wherein the contact screen comprises a data input module, a data storage module and a data processing compute module; it uses the communicating interface to communicate with the PLC to achieve the coordinate axis location control with the locating accuracy 0.002mm; the contact screen also comprises a switch module, a choosing module, a monitoring module and a data following display module.

Description

technical field [0001] The invention relates to a control system of a machine tool, in particular to a control system and method of an economical numerical control machine tool. Background technique [0002] The CNC machine tool adopts the integration technology of control software to integrate PLC in the CNC numerical control system. As the logic control center of various functions of CNC machine tools, PLC will logically sort various motion and function instructions from CNC, so that they can run safely in an accurate, coordinated and orderly manner; The state is transmitted to the CNC, so that the CNC can issue further control commands in a timely and accurate manner. The servo system receives the speed commands provided by the CNC for each motion coordinate axis, and outputs the drive signal to drive the servo motor to rotate through the speed and current (torque) adjustment. , realize the movement of the coordinate axis of the machine tool, and at the same time receive...
