摘要
在进行零件设计时,正确选择形位公差项目及其公差值的确定是一项很慎重的工作,既要根据零件的使用性能和互换性要求,又要考虑生产率和成本的高低。本文仅对形位公差项目的选择进行初步的探讨。
During the part design,the correct choice of geometric tolerance and the determination of the value of tolerances are the very serious work,and it should not only accord to the use performance of parts and interchangeability requirements,but also should consider the level of productivity and costs.This project only makes a preliminary study on the choice of geometric tolerance.
