设计基准与工艺基准不同时对轴类零件位置公差的影响

The Influence to Place Error of Spare Parts of Shaft for Different of Design Datum and Technology Datum

本文针对轴类零件分析了在制订工艺规程时，由于工艺基准与设计基准不同，需要进行位置公差换算的重要性，并结合生产实际，介绍了如何进行位置公差换算，说明位置公差换算对效益有着很大程度的影响。

To spare parts of shaft ,in working out technology rules, for difference of design datum and technology datum,the author analyses importance of conversion of place error,and acoording to produce reality, introduces how to convert place error,explaines that the conversion of space error is very important to benefit.
