摘要
介绍坐标测量机测头性能参数的校准和补偿方法;设计一套基于三维微宏移动平台和测力传感器的校准系统;采用该系统对坐标测量机模拟式测头的触发变形进行实验研究,获得测头的探测力和实际变形量;补偿后的测头系统在XY平面内探测标准测量球的误差不超过0.3μm,满足坐标测量机模拟式测头的校准需求。
A calibration system based on a three-dimensional micro-macro mobile platform and force sensor to calibrate an analogue touch probe is proposed in this paper.The detection force and actual deformation of the probe are obtained.The compensated probe system is verified by the standard measuring ball,and the detection error of the compensated probe does not exceed 0.3μm.The device meets the calibration requirements of three-dimensional analog probe.
