摘要
利用PMAC-PC与IPC工控机组成的上下位机并行双CPU结构,设计集成了一套零件外圆表面在线测量及加工系统.通过PCOMM这个动态链接库建立上位机同PMAC之间的连接,采用多媒体定时器技术与多线程技术,解决了实时数据采集、海量存储、数据上载及显示功能.并在以上技术的基础上完成了上位机测控系统软、硬件设计,可以实现零件圆度误差的在线测量.为推动开放式数控系统在精密加工中的应用,实现加工测量一体化打下了基础.
Using double CPU configuration consisted of PMAC-PC and IPC, a system for online measuring and machining of cylindrical surface of parts was designed. The main computer was connected with PMAC via DLL of PCOMM. Using multimedia timer and multithreading technologies, real-time gathering data, mass memory, data upload and display function, and so on have been realized. Software and hardware design of the main computer MACSYM are developed based on the above techniques, and online measurement of roundness error of parts can be achieved, which provides the foundation for promoting open CNC application in precision machining and the realization of machining and measurement integration.
