自从“表面形状和位置公差代号及其注法”(GB1182-74)颁发以来,由于它有许多优点,因而深受广大工程技术人员和生产工人的欢迎。形位公差是评定产品质量的一项重要指标,随着生产的发展,产品精度的提高,形位公差的作用日益显著。如何在设计工作中贯彻形位公差新标准,如何对形位公差进行合理标注,是一个值得讨论的问题。下面就当前图纸设计上存在的一些问题,谈一些看法。一、标注明确,解释唯一,要求合理图纸是产品制造的依据,因此图纸必须标注明确,解释唯一,同时也应该要求合理。如果图纸提出的要求不切实际,在生产中难以实施或不能实施,就会引起设计、工艺、检验三者的争执,应尽可能加以避免。
Since its issuance of “Code for Surface Shape and Position Tolerance and Its Injection Method” (GB1182-74), it has been well received by the majority of engineering technicians and production workers for its many advantages. Geometric tolerance is to assess the quality of an important indicator of product, with the development of production, product accuracy, shape and tolerance increasingly significant role. How to carry out the new standard of form and position tolerance in the design work and how to reasonably label the form and position tolerances is a question worth discussing. Below on the current design of the drawings on some of the problems, talk about some ideas. First, a clear label, explain the only requirement for a reasonable drawing is the basis for product manufacturing, drawings must be clearly marked, explain the only, but also should require reasonable. If the drawings put forward the requirements unrealistic, difficult to implement in the production or can not be implemented, it will lead to the design, technology, testing the three disputes, should be avoided as much as possible.
