摘要:

为解决航空制造领域复杂零件的加工难题,针对研制的复合进给电解加工机床,开发了基于PC( personal computer,个人计算机)和PMAC(programmable multi-axles controller,可编程多轴控制器)运动控制卡的开放式数控系统。基于虚拟仪器技术及其开发环境LabVIEW平台,遵循模块化设计思路,采用ActiveX自动化技术和CLF (call library function,调用库函数)节点设计了复合进给电解加工机床控制系统的人机交互界面,通过调用PMAC运动控制卡中的服务程序PmacServer,实现上位机与PMAC运动控制卡之间的功能交互。为了验证该控制系统的可靠性和运行稳定性,使用激光干涉仪进行了实验测试。实验结果显示,该控制系统响应迅速,运行稳定,人机交互界面易于操作;机床运动误差控制在-5~5 μm内,重复定位误差小于2.3 μm,能够满足航空发动机叶片的电解加工精度要求。研究结果在电解加工领域具有重要工程应用价值,可以为新一代高性能电解加工机床的设计提供参考。

Abstract:

To solve the problem of complex parts machining in aviation manufacturing field, an open CNC(computerized numerical control) system based on PC(personal computer) and PMAC(programmable multi-axles controller) motion control card was built for the compound feed electrochemical machine tool. Based on the virtual instrument technology and its development environment LabVIEW platform, following the modular design idea, the human-computer interaction interface of the control system for compound feed electrochemical machining machine tool was designed by using ActiveX automation technology and CLF (call library function ) node. The function interaction between host computer and PMAC motion control card was realized by calling the service program PmacServer in the software. The experiments were carried out to verify the reliability and stability of the control system by using a laser interferometer. The results showed that the control system responded quickly and stably, the human-machine interface was easy to operate, the motion error of the machine tool was controlled within -5 to 5 μm, and the repetitive positioning accuracy was less than 2.3 μm, which met the accuracy requirements of high precision electrochemical machining. The research results have important engineering application value in the field of electrochemical machining, which can provide a useful reference for the design of a new generation of high performance electrochemical machine tool.
