一、前言虞文华等学者通过对伺服系统动态特性对数控机床圆轨迹的加工精度影响机理进行研究，认为在不考虑机床自身的几何精度的前提下，系统的轮廓跟踪误差主要是由伺服系统的动态特性和联动轴之间的动态参数不匹配而引起。因此，为提高机床的轮廓加工精度，国内外的专家... I. Preface Yu Wenhua and other scholars through the dynamic characteristics of servo system on the CNC machine tool circular path machining accuracy of the impact mechanism that does not consider the geometric accuracy of the machine under the premise of the system’s contour tracking error is mainly by the servo system dynamics The characteristic and the dynamic parameters between the linked axes do not match. Therefore, in order to improve the contour machining accuracy of machine tools, domestic and foreign experts ...
