摘要
针对多轴联动电火花加工数控系统的设计要求,开发了一种基于PC和Linux开放式平台为上位机、可编程运动控制器(PMAC)为下位机的五轴联动电火花加工数控系统.利用Linux开源性好的特点,设计了环境友好的人机交互操作界面以及各类完成非实时任务的程序模块等;基于PMAC系统开发了伺服进给回退运动、主轴高速抬刀运动、五轴联动及各类摇动程序等.通过将数控系统应用于五轴联动电火花加工机床,进行了闭式整体涡轮叶盘样件以及窄缝窄槽等典型零件的加工实验,取得了良好的加工效果.
This paper introduced a new 5-axis computer numerical control （CNC） system for electro-dis-charge machining （EDM） based on Linux. In the system, a motion controller of programmable multi-axis controller （PMAC） was employed as the subordinate computer, and a PC-based platform running on the Linux operating system was applied as the principal computer. An environment-friendly human-machine operating interface and various software modules used to implement non real-time tasks were developed based on Linux. Some key programs which serve controlling servo motion, main axis＇ high-speed jump motion, 5-asix motion and rolling motion were also designed based on PMAC. By being applied to 5-axis EDM machine and carrying out the experiments of processing shrouded turbine blisk and narrow slot, the system validated its performance of strong real-time ability, high stability and reliability as well as stable control for main axis＇ high-speed jump motion.
