1975年发布了“形位公差”试行标准G B1183～1184-75,1980年经过修订后转为正式的国家标准GB1182～1183-80。试行标准是先定义形位误差,再引伸出形位公差的定义,而正式标准则与此相反。我们按现行的“形位公差”标准的理论系统来授课,已有三年多的时间了,通过前一段的教学实践,现在来归纳和总结一下经验和教训,我想对今后教授好这门课程将会是有益的。
In 1975, the “Goniopore Tolerance” Trial Standard G B1183 ~ 1184-75 was released. In 1980, it was revised into the official national standard GB1182 ~ 1183-80. Trial standard is the first definition of geometric error, and then extended the definition of geometric tolerance, while the official standard is the opposite. We have taught for more than three years according to the current theoretical system of “Form and Position Tolerance”. Now we can summarize and sum up experiences and lessons through the teaching practice in the previous period. I would like to teach this course in the future It will be helpful.
