我们在修订《机床辅助工具》部标准中,按上级指示,贯彻了GB1182—74《机械制图表面形状和位置公差代号及其注法》。我们边学边干,在标准中先后采用了符号框格这种新的形、位公差标注法。通过这个阶段的实践,我们体会到新注法具有符号形象化、注法简单、说明问题清楚、一目了然等许多优点,无论对设计、制造、检验工作都提供了方便条件。并且也便于国际间的技术交流。下面我们谈谈在采用新注法中的几点体会。
We revised the “Machine Tool Assistants” Department of standards, according to the instructions of the higher level, the implementation of the GB1182-74 “mechanical drawing surface shape and position tolerance code and its injection method.” We learn while doing, in the standard has adopted a symbolic box this new shape, bit tolerance tagging method. Through the practice of this stage, we have realized that the new annotation has many advantages, such as symbolic visualization, simple annotation, clarification of the problem, and being clear at a glance, providing convenient conditions for design, manufacture and inspection. And also facilitate international technical exchanges. Below we talk about the use of the new method in a few notes.
