摘要
为了降低低副机构的加工成本，作者导出了机构各构件的制造误差与机构输出误差之间的函数关系，按加工误差的分布规律，确定了满足使用要求的经济加工精度的方法。实例表明：按本文叙述的方法确定加工精度可降低加工成本。
In order to decrease manufacturing cost the author has deduced the functional relationbetween machine elements and mechanism error, and has stated the method to determinemechanism economic manufacture error to meet practical need by means of manufacturing errorlaw. The example of how to do shows the method stated can decrease manufacturing cost.
