Abstract

A follower with any rotational curved surface is used to develop a spatial double-end cam, in this paper. The follower surface can be the mathematical equation of any rotational curved surface. According to envelope theory, the mathematical model of the proposed double-end cam was obtained by a family of the follower surfaces and equation of meshing. In addition, using tooth contact analysis, kinematic errors of the proposed cam mechanism were investigated through assembly errors between the cam and followers. Moreover, results of kinematic errors using assembly errors for the doubled end cam mechanism were studied. A software package was used to assemble the follower and cam of the proposed double-end cam mechanism. The required cutting paths were generated by computer-aided manufacturing program. The proposed double-end cam is really manufactured and assembled by a CNC five-axis machine. A numerical example was given to illustrate the application of the procedure.
