摘要
机械制造中,工件在夹具中定位时,定位误差对工件的加工精度影响很大,其中工件以组合表面定位形式较多,其定位误差应进行综合分析。本文以常见的一面两孔组合定位为例,说明其定位误差的计算方法。
In machinery manufacturing, positioning error has great influence on machining precision of workpiece in fixture positioning, there are more forms of combined surface positioning, and making a comprehensive analysis of positioning error is needed. Taking the common one side two holes location as a ease, illustrating the calculating method of positioning error.
