摘　　要：Testing the parts of mechanical products and ensuring their accuracy to the design requirements are essential to products’ quality, market competitiveness and manufacturers’ maximum economical benefits from these products. One of the latest subjects of study in the area of precision measurement is the testing of parts to follow the relative requirements, viz. design requirements for the size tolerance of size features and related geometrical tolerances of the central feature, including the envelope requirement, maximum material requirement and least material requirement. The article analyzes test methods for parts to follow the envelope requirement or maximum material requirement, as well as further requirements of geometrical tolerances for its central feature. The method is effective in improving product quality and rejecting unqualified parts.为了确保机械产品的质量 ,提高机械产品的市场竞争能力 ,使企业从产品中获得最大经济效益 ,必须对组成产品的零件进行检测 ,以达到设计的精度要求 .对采用相关要求零件的检测是精密测试领域中最新的研究课题 .相关要求是尺寸要素的尺寸公差与其相应的中心要素的形位公差相互有关的设计要求 ,包括 :包容要求、最大实体要求和最小实体要求 .分析论述了采用包容要求或最大实体要求并对其中心要素的形位公差有进一步要求零件的检测方法 .为避免误收 ,保证和提高产品质量 ,提供了有效途径 .
