摘要
为更好获取主轴径向跳动信号,提高测试系统中误差分离与补偿的可靠性和稳定性,采用正交设计进行主轴径向跳动工况研究。结合工厂实际测试需求,选取合适因素及因素水平构建正交设计方案表,以减少实验次数;利用无线温度采集传输系统及激光位移传感器采集系统对主轴进行径向跳动测试。通过对装夹刀具正交实验和不同刀具正交实验结果进行极差分析,确定主轴在5000r/min,运转120min,且安装镗孔刀具工况下,主轴的径向跳动最大,测试效果最优。
In order to better get the spindle radial motion errors and improve the reliability and stability of the error separation and compensation in the test system,the orthogonal design was used to study the conditions of spindle radial motion. Combining the factory test requirements,the appropriate factors and factor levels were selected to determine the orthogonal design table and reduce the number of tests. Wireless temperature acquisition and transmission system and laser displacement sensor data acquisition system was used for spindle radial motion test. By means of range analysis of the clamping tool orthogonal test and the different tools orthogonal test,the optimal condition of spindle radial motion test is in 5000 r / min,running for120 min and installing the boring tool.
