ISO 2692:2021 产品几何技术规范(GPS). 几何公差. 最大实体要求(MMR)、最小实体要求(LMR)和可逆要求(RPR)的最新版本是哪一版?
最新版本是 ISO 2692:2021 。
This document defines the maximum material requirement (MMR), the least material requirement (LMR) and the reciprocity requirement (RPR). These requirements can only be applied to linear features of size of cylindrical type or two parallel opposite planes type. These requirements are often used to control specific functions of workpieces where size and geometry are interdependent, for example to fulfil the functions “assembly of parts” (for MMR) or “minimum wall thickness” (for LMR). However, the MMR and LMR can also be used to fulfil other functional design requirements.
