一、问题的提出轴系回转精度的测量通常有3种方法:基准件单点测量,多方位误差分离技术和多传感器误差分离技术。其中的3传感器技术,可以将轴系回转误差运动从包含有基准件形状误差的总的测量信号中分离出来,并避免了多方位技术要求多次装卡基准件,要求误差运动重 First, the issue put forward Shaft revolution accuracy measurement usually has three kinds of methods: a single point of reference measurement, multi-directional error separation and multi-sensor error separation techniques. One of the 3 sensor technology, the axis of the gyratory error movement from the reference shape error of the total measurement signal is separated, and to avoid the multi-directional technology requires multiple mounting card reference, the error required heavy exercise weight
