摘要
通过分析定位误差ΔDW的组成,提出简化工件在机床夹具中的定位误差的计算方法。由分析机床夹具定位基准的移动方向与工序基准同定位基准间的距离尺寸无关或有关两种情况,探讨确定机床夹具中的定位误差计算式中加、减符号的方法。得出简化工件在机床夹具中的定位误差的计算方法。
From analysis component of the position error ADW, it is introduced the thinking of which simplifies workpiece position error calculating method within the machine tool＇s fixture. Based on analysis relationship of which the shifting direction of position datum is or not is to the distance dimensions between process datum and position datum, have researched on method define the sing about plus or minus within the calculating formula of the machine tool＇s fixture position error. It is set up a calculating model of which simplifies workpiece position error calculating within the machine tool＇s fixture.
