摘要
《形位公差》和《公差原则》国家标准对图样上给出的尺寸公差与形位公差的关系规定了独立原则、包容原则和最大实体原则。而最小实体原则尚未被纳入。本文拟就最小实体原则及其应用进行探讨。
The independent principle, envelope principle and maximum material principle were given in National Standard of Geometrical Tolerances and Tolerances principles. These three principles show the relation between size tolerance and Geometrical tolerances in drawings. However, least material principle has not been contained in National Standard. This paper discusses least material principle and its application.
