AbolishedGeometrical tolerancing--Maximum material requirement，least material requirement and reciprocityrequirement
形状和位置公差 最大实体要求、最小实体要求和可逆要求
Application Summary AI generated
This standard specifies the definitions, symbols, and application rules for maximum material requirement (MMR), least material requirement (LMR), and reciprocity requirement (RPR) in geometrical tolerancing. It is applied in mechanical engineering and manufacturing to control the functional interchangeability of parts, particularly for fit conditions like clearance or interference, by allowing tolerance adjustments based on actual material size. The standard is used in design, production, and quality inspection contexts to optimize part assembly and reduce manufacturing costs while ensuring functional requirements.
