测量圆度方法的新探
|
摘要
高精度的圆度测量是在英国泰勒圆度仪上完成的。中心架、光学分度头、万能工具显微镜也可以测圆度。它是采用工件旋转,打表测圆度,测量精度较低。该方案采用同圆度仪的测量方式,即工件不转动,头架转盘安装电感测头,接触圆柱面,绕被测圆柱旋转进行圆度测量。由计算机完成对头架转盘转动的系统误差的补偿,提高了圆度的测量精度。
High-precision roundness measurement is done on the British Taylor roundness meter. The center frame,the optical indexing head, and the universal tool microscope can also measure the roundness. It uses the rotation of the workpiece, the roundness of the meter is measured, and the measurement accuracy is low. The program adopts the measurement method of the same roundness meter, that is, the workpiece does not rotate, the head frame turntable is mounted with the inductance probe, the cylindrical surface is contacted, and the roundness measurement is performed around the measured cylinder rotation. The computer compensates for the systematic error of the rotation of the headstock turntable, and improves the measurement accuracy of the roundness.
