【摘要】 在产品的机械加工工艺过程中 ,并联设计尺寸链是普遍存在的 ,分析计算工艺尺寸偏差时 ,并联关系的二环尺寸链具有决定性的重要作用。结合实例提出了求解工艺尺寸及其公差 (偏差 )的基本思路 ,供机械加工工艺人员参考更多还原

【Abstract】 The dimension chains designed in parallel way exist pervasively at the mechanical process course of products.Two-loop parallel dimension chains are of vital importance as we analyses and calculate the deviation of process dimensions.This paper puts forward with practice the basic idea of seeking its solution in order to provide some consult to technicians.更多还原
