摘要
提出了一种尺寸与公差的形式化表达模式,在定义尺寸与公差说明中,引入并构造了零件公称形状的尺寸与公差元素集及与其相应的实际元素集和外部拟合元素集,以进行尺寸与公差检测。
A formalized scheme for representing dimensions and tolerances is proposed in this paper.This scheme is approximately consistent with the existed standards and is extendible to some extent.In order to inspect dimensions and tolerances,dimension and tolerance elements,their corresponding actual elements and externally fitting elements are introduced in the dimension and tolerance specification.
