定位误差对工件加工精度的影响及控制

Effect of Position Error on Workpiece Machining Accuracy and Its Control

分析并指出了定位误差的构成及产生原因,结合生产加工案例,对几种定位方案的定位误差进行计算,分析其对被加工工件位置尺寸公差的影响,并提出控制定位误差的方法。

This paper analyzes and points out the compositionand causes of positioning errors. Combining the production andprocessing cases, the position errors of several positioning programsare calculated, and the influence of position tolerance on theworkpiece is analyzed. The method of controlling positioning erroris proposed.
