Abstract

Flow forming is normally used to produce seamless tubes of high precision. Rocket launcher cases, cartridge case, missile casing, rocket nose cones are the typical examples of aerospace and defense sector which are made by flow forming process. Literatures state that the flow forming is influenced by many parameters like leading/attack and trailing/smoothing angles, rotational speed, axial feed, forming depth etc. The understanding of effect of parameters on the process is quite important because it is useful for the designing of tools (rollers and mandrel) for various material and geometrical conditions. Hence, the present analysis is carried out for different leading and trailing angles. The effect of leading and trailing angle is studied for von mises stress and equivalent plastic strain. It has been noted that as the leading angle increases the von mises stress is gradually increases, whereas equivalent plastic strain decreases. It also observed that as the trailing angle increases the von mises stress remains almost constant, while small reduction is found in the maximum equivalent plastic strain.
