摘要
本文分析了我国数控机床技术发展和数控技术培训设备现状,说明了培养高级数控技术应用人才的迫切性,以及制约开展数控高级培训的瓶颈原因。阐明了三菱数控技术培训平台对开展从数控编程和实操的基础学习,到系统调试和伺服调整的专业培训,以及机床静动态特性研究等从低到高多层次数控培训的必要性和重要性。在完成数控培训平台基本调试和伺服调整的基础上针对北方工业大学-三菱电机CNC技术培训中心将要开展的数控培训和应用研究进行了基础研究工作。
深入研究和系统分析了三菱数控系统参数设定的方法。基于三菱数控系统伺服驱动器的特点,开发了伺服参数调整的测试系统。研究了三菱数控系统伺服参数调试的新方法,在传统伺服调整过程中,增加了伺服环运动性能的图形交互功能,对伺服调试过程是一个有益的反馈和补充;速度环参数调试过程和实验结果表明,通过图形反馈信息进行伺服特性参数调整具有更高的效率和精度。
在分析数控机床的误差来源和误差补偿方法的基础上,研究了三菱数控系统下数控机床的综合误差补偿技术,并用激光干涉仪测量了加工中心XH7132直线轴的定位误差,对三菱数控系统机械误差补偿参数进行了设定,有效提高了数控机床的运动精度。
现代数控机床对速度和精度要求越来越高,机床传动系统的负载惯量计算成为在机床结构设计、电机选型和伺服特性调试等阶段重要考虑的因素之一。基于对数控机床各种常用传动结构的分析和计算公式的研究,开发了进给系统惯量计算软件(NCUT ServoDesign System),可以作为系统设计的软件工具包。该软件具有传动系统惯量计算和伺服电机选型功能,为方便今后的设计和研究工作奠定了基础。

Mitsubishi CNC system training platform is a necessary and important equipment to training of program and operation, study of system debug and servo adjustment, and researching of static and dynamic characteristics of machine . Based on the system debug and servo adjustment of the CNC system training platform, the fundamental research on CNC system is finished according to the CNC training in the NCUT-Mitsubishi CNC training center in the future.
The method of parameter setting of Mitsubishi CNC system is deeply studied and analyzed. Based on the characteristic of the Mitsubishi servo driver, the testing and analysis system of Mitsubishi servo adjustment is developed. A new servo parameters adjusting method of Mitsubishi CNC system is studied and the graphic interactive function is added in the traditional servo adjusting procedure, which is a beneficial feedback and supplement. The servo debugging process and experiments results show that this method is much more efficiency and precision than the traditional methods.
After analyzing the error source and compensation method, integrated error compensation technology of machine controlled by the Mitsubishi CNC system is studied. Location error of axis of the XH7132 vertical machining center has been measured by laser interferometer. The error parameters have been set so that the positioning precision of the CNC machine has been enhanced effectively.
The requirements for speed and precision of modern CNC machine become higher and higher. The load inertia calculation becomes more and more important during machine structure design, motor selection, and servo adjustment.
