Problems solved by technology

[0003] At present, a lot of research has been done at home and abroad on the control of the processing state of the CNC system in the processing process, but no CNC system with controllable processing state has been found in the market. The reason is that various processing state signals are collected during the processing process. Not only is it more complex and difficult to operate, but also requires high real-time performance and fast response

Abstract

This invention unfurls a kind of embedded model numerical control flat roof of processing state controlling politic integration and its control method. The hardware system of the numerical control flat roof includes the motion control module with PC/104 - Plus interface, the CPU module based on PC/104 - Plus, the multifunction data collecting module based on PC/104 - Plus, the CAN communication module based on the PC/104 - Plus, and the Profibus communication module. The controlling method is: the main system translates the operation instructions into motion control messages after receiving them, and sends the progressing messages to the motion control module, finally sends them to the processing servo axis electrical engine drive, the chief axis electrical engine drive and the handwheel; send the motion control messages to CAN communication module and the Profibus communication module, and send outside to the motion servo axis electrical drive. This invention can realize that the processing state is controllable and the progressing course is intelligent.

Description

technical field [0001] The invention belongs to the category of digital control systems, and specifically refers to an embedded numerical control platform integrated with machining state control strategies and a control method thereof. Background technique [0002] As the core enabling unit supporting the physical functions of the computer integrated manufacturing system, the numerical control system is developing in the direction of open structure, integration, intelligence and networking. The introduction of modular technology, embedded technology, and intelligent control technology has made the previously dedicated and closed traditional CNC system gradually become a complex control platform that integrates various advanced functional units and interactive interfaces. The high-performance CNC platform will no longer be limited to precisely controlling the movement direction, feed speed and displacement of the execution parts, but also requires t...
