Abstract :

Cold pilgering is one type of metal forming process in which the thickness and diameter of the tube reduces up to 65 to 70 percentage. It is generally chosen for its dimensional accuracy controlled by ratio of diameter to thickness reduction. In pilgering process, the profile of the roller die and mandrel is very important because the outer diameter surface finish depends on the roller die profile and inside diameter surface depends on the mandrel profile. This article focuses on the stress analysis of different profiles of mandrel like: Linear (Taper) and Parabolic (Quadratic) Profiles.
