“…Many scholars have used plate forging to produce unequal thickness parts. Generally, parts with thickened walls or functional elements can be fabricated by the combination of drawing/flanging with upsetting [1][2][3][4][5][6][7][8]. In this combination, a vertical wall is firstly formed by drawing or flanging, and then an upsetting operation is taken to increase the wall thickness or form functional elements.…”

This paper studies the process of a five-step spinning to thicken the edge of the disc-like part. By using finite element simulation and experiment, the sectional shape and flow-line distribution of the rim were studied. The results showed that the flow lines of the cross-section of the formed part are distributed along the shape of the part. The disc-like part with thickened rim can be well formed by a multi-step spinning process. A large bottom radian of roller groove can lead a folding in the first step and a reduced r can overcome the folding. An over-small angle αin step 2 will lead a pit defect, it can be solved by increasing the angle.
