| Abstract: | With the development and extensive application of CAD, CAM, FMS and NC in mechanical design and manufacture, converse envelope has become more important. The principle of solution and geometry model of common types, i.e. envelope type, extreme value type, intersection type, disk type, finger type and column type, are presented here, together with the envelope equations and the conditional envelope equations of the curve group of envelope type. Also, the method to resolve the envelope of curve group produced by donkey head -like curve consecutive motion is explained in detail, and their concrete application is demonstrated through examples. |
