| 摘 要： | 运动学标定是提高虚拟轴机床精度的重要技术手段，结果机床加工作业的特点，提出一种对虚拟轴机床进行预标定有效方法。其特点是通过改变静平台铰链点的位置参数校准静平台坐标系相对于工作台坐标系的姿态，从而消除因静平台坐标系位姿偏差所导致的末端输出误差，这有利于提高以后标定算法的有效性，为标定作好准备。

| Abstract: | Kinematic calibration is an important mean to improve the accuracy of Virtual Axis Machine Tool. This paper presents a method for calibration of Virtual Axis Machine Tool through its working characteristics. This method can adjust the orientation of the fixed platform reference frame to make it parallel to the working table reference frame, by changing the positions of U-joints on the fixed platform. So that,the error due to the orientation offset between these two reference frame can be decreased. Keywrods:virtual axis machine tool error analysis kinematic calibration calibration experiment |
