【摘要】 对复杂平面切割类零件进行结构特征分类和分析,通过切割结构的快速定体、定形和定性,探讨复杂切割类零件快速建模方法和途径,提出斜孔、斜槽在建模时的定位基准建立方法,适用特征造型的三维设计平台中的模具切割类零件的CAD/CAM建模。更多还原

【Abstract】 To analyse and dassify complex plane surface parts are used to define the structure feature, shape and feature classification of cutting parts. Giving the general methods will be appliced in fast model drawing in CAD/CAM .It solves this problem that oblique line or slope surface strcture and point out the key of modeling cut parts .It is a better way to build model-parts in CAD/CAM with feature function.更多还原
