基于PMAC的超精密磨床开放式数控系统的研究

摘要

根据超精密磨床的结构特点和功能需求，分析了基于PMAC的开放式数控系统的硬件结构，软件组成及软件开发的关键技术；利用Visual C＋＋6.0，采用模块化设计思想开发了超精密磨床的数控系统软件，并对软件模块的功能和实现方法进行了较为深入的探讨，试验结果表明：该数控系统的功能齐全，可以满足超精密磨床的要求。%According to the structure characteristics and functional requirement of the ultra-precision grinder,the hardware struc-ture and software form of the PMAC-based open computer numerical control (CNC)system,as well as the key techniques of software development were analyzed.The software of CNC system of the grinder was developed by using Visual C++6.0 and using the desig-ning idea of modularization.The function modules and the implementation ways of software were discussed in depth.Experimental re-sults prove that the open CNC has full functions,which can meet the requirement of the ultra-precision grinder.
