选定公差与配合对机件加工成本的影响

The Effect of Determinating Tolerance and Mating of Machine Parts on Their Cost

根据实际情况恰如其分地选择零件的加工精度和机件间的配合关系,对保证产品的质量和控制加工成本有着不可忽视的意义。笔者根据实践经验提出了正确选择公差与配合的原则。

Determinating tolerance and mating of machine parts not only affect their manufcturing cost at some extent and also their quality and performance. The author of this paper proposes some principles for making the determination according to his experiemnents.
