自由形状基准特征部件几何尺寸与公差基准系创建规则初探

Study on Creating Rule of Free-form Datum Feature Parts Geometric Dimensions and Tolerance Datum System

通过实践案例介绍具有自由形状基准特征部件的基准系创建思路,以及这些思路的原理和相关部件基于基准系标注的检测方法。文中强调了检具的作用,以及基准系创建需要遵从设计实践功能意义的观点。

Through practice cases, the reference system creation ideas with free-form fiducial feature parts, the principles of these ideas, and the detection methods of related parts based on the reference system labeling are described. This paper emphasizes the role of the gage and the point that the creation of the reference system needs to follow the functional significance of design practice.
