In GD&T,profile tolerancedefines a uniform boundary around a surface within which the elements of the surface must lie. Profile is a complex tolerance that simultaneously controls afeature‘s form, size, orientation, and sometimes location. Profile is a three-dimensional tolerance that applies in ...
完全不规则零件的基准系标注 datum definition of irregular components 完全不规则零件的基准系建立需要用特定的夹具(也就是功能夹具),图纸需要指定相关支撑位置,首先指定一个基准系,其他基准目标的位置用基本尺寸的方式标注到基准系。如图6所示 图6完全不规则零件的基准建立 第二、第三基准的标注Secondary and tertiary...
This page explains the differences between size tolerance and geometric tolerance, as well as the advantages of geometric dimensioning and tolerancing, and the principle of independency. “Learning GD&T From Scratch,” provided by KEYENCE, walks you thro
ASME Y14.41—2012 Digital Product Definition Data Practices Y14.41定义了基于三维的数字化产品定义的基本准则,奠定了三维数据贯穿设计、制造和检测等全方位应用基础,既适用于三维产品研发模式(Model Only),也适用于三维与二维混合的研发模式(Model and Drawing)。三维数字化产品定义,除了模型数据、修订历史之外,还包括...
