-
摘要: 对数控铣床加工过程中的动态轨迹误差进行了研究,介绍其产生原因和基于MATLAB的仿真计算方法,并给出了2坐标和4坐标典型运动轨迹在不同进给速度下的动态轨迹误差的仿真建模和计算实例.仿真结果表明,高速铣削加工中的动态轨迹误差所引起的工件轮廓误差是不可忽略的误差因素.Abstract: The sources of dynamic path error of NC machine tools during milling process are analyzed, a simulating method based on MATLAB is introduced. The simulating modules and calculating methods of some typical 2-axises and 4-axises tracks at different feed speeds are also described. The simulating results show that, during high speed milling process, the dynamic path error of NC machine tools cannot be neglected.
