位置度误差主要是指被测实际要素对其理想要素的变动量,理想要素相对于基准位置由理论正确尺寸决定。目前,坐标测量机的广泛使用,给位置度的测量带来了极大的便利。但是,一般坐标测量机主要是针对零部件的测量,准确度不高,对于位置度量规的测量难以胜 Position error mainly refers to the actual element of the measured changes in its ideal element, the ideal element relative to the reference position by the theoretical correct size decision. At present, the widespread use of CMM has brought great convenience to the measurement of the position degree. However, the general coordinate measuring machine is mainly for the measurement of parts, accuracy is not high, the measurement of the position gauge difficult to win
