Development And Study Of Numerical Controlling Interface Of Large-scale Drinding Machine Based On PMAC

With the rapid development of modern manufacturing, the weakness of traditional CNC system becomes apparent increasingly, such as, compatibility, expandability, inflexible human-machine interfaces and so on. In order to meet the need of the market, the research of open architecture CNC systems is becoming one of the most important directions of CNC technology. The goal of open architecture CNC system is to build a modular, reconfigurable and expandable architeture of CNC system and make the design and implement of the special machine more rapid and precise with the background of rapidly changed market. In the thesis, some key technology on the design and implement of the software of the numerical control drill machine building on the Programmable Multi-Axis Controller are discussed, including the architeture of open CNC system, the fundamental principle, software, etc. Following are the main work:First, on the basis of analysis on the essence functions, expandability, distribute application of international open CNC projects(mainly on Open Modular Architecture Controller), the method making use of PMAC to structure NC implanting the architectural PC type open architecture numerical control drill machine system have been brought forward. That is to say that the motion control panel is intervened in PC expansion slot being applied universally. PC will realize non-real time part function including the consumer interface, the document administration and communicating and so on; and the Real time control function is born by the motion control panel. Having studied now available a technology developping software upper Windows platform, on the basis of adopting the time division parllel processing technology and the multiple interrupted parllel processing technology, making use of high-grade programming language of VB6.0 and self simultaneous open control panel function warehouse, the numerical control system interface that the consumer needed is developed upper the Windows platform.The CNC system with friendship.integrated and systematical interface, integrates numerical control system with peculiar function module. It provides a friendly.integrated system interface in which inter-consultation can be done in Chinese in the computer environment.
