| 摘 要： | 针对机床高速旋转主轴的安装偏心及各种外界干扰对热误差精确测量的影响,本文选用了精度较高的电容式位移传感器及NI数据采集卡,基于LabVIEW平台开发了一套机床温度和位移数据实时检测系统。该检测系统可实现在主轴高速旋转下位移数据的高速率采样,并采用软件数字滤波方法对位移数据处理。最后将该检测系统进行实验测量,实验结果表明该检测系统具有一定的实用性。

| Abstract: | Based on the LabVIEW platform,the paper develops a new machine tool thermal error real-time measurement system by using high-precision capacitive displacement sensor and NI Data Acquisition Card to meet the effects of the spindle bais and external interference in the high-speed rotation.The system adopts IIR filter which can effectively eleminite outside interference factors to acquire data in high sampling rate.Finally,the system has been applied to measure the machine tool spindle thermal error in the exp... |
