Research on Generation Method of Globoidal Cam Surfaces Based on Five-axis NC Machine

According to the analysis on the generation motion of globoidal cam surfaces,two kinds of general five-axis NC machines can be used to equivalently machine globoidal cam surfaces:one kind of machine has rotary table-pivoting spindle head and the other has double rotary table. The motion coordinates of two kinds of machines while generating surfaces is calculated based on the mathematic model of globoidal cam surfaces and the generation process is simulated in the paper.
