浅析机械零件尺寸标注中基准的选择

Discussion on Selection of Basis in Dimension Determination of Mechanical Parts

阐述不同类型的机械零件尺寸其设计基准的选择原则,同一机械零件因尺寸基准选择的不同而导致不同的设计效果,进一步说明尺寸基准选择的重要性。

This article gives selection principles of basis for different types of dimensions as different basis selections for the same mechanical parts will lead to different design results. The importance of selection in dimension basis is emphasized.
