On the basis of the conjugate engagement theory of globoidal indexing cam mechanism
a kind of profile modification method of globoidal indexing cam is put forward based on traditional generating method.By the modification of the trajectory of cutting tools in the engaging-in and engaging-out section and cut more of the corresponding areas in the dwell region to modify the cam profile.Moreover
modification program of different types of globoidal indexing cam are presented
a theoretical basis for the machiningof globoidal indexing cam modification is provided.
