Abstract: Shaping globoidal cam is the key in manufacturing of the globoidal cam indexing device.The traditional method is bar machining,which can hardly meet the producing need for its low rate of material exploitation,low productivity and high cost.Isothermal extrusion of globoidal cam is a kind of technique aiming at Net-Shape and Near-Net-Shape.In this paper,MSC.Marc software is used to simulate numerically the globoidal cam isothermal extrusion.The influences of different model cavity concave wedge angle a on the performance of fulling billets are analyzed.The research provides an important basis for the realization of globoidal cam isothermal extrusion and model structure optimization.

Key words: globoidal cams, isothermal extrusion, numerical simulation, optimization of structure
