Abstract: The precision of CNC machine tools largely depends on the performance of the servo system. Based on the analysis of the performance and effect factors of the servo system, the paper put forward the fundamental principle of adjusting the servo system up to the best performance. Meanwhile, it discussed some measures to improve the performance of the servo system, and provided the idea and method of the servo system application.
