加工中心几何精度检验的探讨

Study on geometric test standard for machining centre and some relatred advices

本文简要的论述了加工中心整机几何精度检验合理的实施方法， 分析了新颁国际标准（ 草案） ＩＳＯ／ＤＩＳ１０７９１ 的几何精度部分同原机械工业部部颁标准ＪＢ／ＧＱ１１４０ － ８９ 加工中心精度部分二者的差异与劣优， 差重指出ＩＳＯ／ＤＩＳ１０７９１ 新标准仍有漏检或易引起争议的一些尚待商榷的问题， 提出了制订我国加工中心几何精度检验新标准的具体建议。

This paper compares the part of geometry accuracy in the new international standard (draft) ISO/DIS10791 with that of the machining centre accuracy in the old mechanical engineering department standard JB/GQ1140-89. Although the new standard is better than the old one, there are some uncertain questions or pending further discussion in the new one. Some advices are given.
