【Abstract】 In view of the complexity about the working camber, a new method of modeling the dividing cam of arcuate surface is given. Main parameters are calculated by Excel, and their variables are imported in the expression of UG by notepad, and then the modeling is generated by using the expression and the features in UG. A series of cams can be designed by modifying the main parameters. Thus the complex designing is reduced, the designing period is abbreviated, and the designing precision is increased.更多还原
