定位误差的运动学解释及工件以回转面定位的定位基准

^^Kinematical Explanation of Workpiece Location Error and Location Reference of Workpiece Located by Its Rotary Surface

本文阐明了当工件以回转面定位，计算定位误差时，取定位基准或为回转面某一母线，或为其中心线，计算结果是相同的。进而从运动学原理上对定位误差进行了解释。

With workpiece located by its rotary surface , either the rotary surface or its center line is regarded as the reference of location , the calculating results of location error are the same. The location error is explained on kinematics in this paper.
