摘要： 使用超精密数控机床加工零件时，应用误差补偿技术能够显著提高加工精度。本文首先概述了数控机床的误差补偿原理和误差补偿流程，在此基础上通过仿真实验，证明了使用误差补偿技术后，数控机床的实际加工轨迹更加趋近于理想轨迹，进一步提高了加工精度。随后设计了基于UMAC控制器的超精密数控机床控制系统，并进行了PID参数调试，确保机床运动特性最佳。最后验证了系统基本功能，确保数控系统的点动功能、状态监视功能等均可以正常实现。
Abstract: When machining parts with ultra-precision CNC machine tools, the application of error compensation technology can significantly improve the machining accuracy. This paper first outlines the error compensation principle and error compensation process of CNC machine tools. On this basis, it is proved by simulation experiments that after using error compensation technology, the actual machining trajectory of CNC machine tools is closer to the ideal trajectory, which further improves the machining accuracy. Subsequently, an ultra-precision CNC machine tool control system based on UMAC controller was designed, and PID parameters were debugged to ensure the best kinematic characteristics of the machine tool. Finally, the basic functions of the system are verified to ensure that the jog function and state monitoring function of the CNC system can be realized normally.
