Abstract

Nowadays, step reduction in the manufacturing process is an important issue because it reduces both the cost and time. The objective of this research is to reduce the steps used in the cold forging process of a socket head screw from 3 steps (existing design) to 2 steps (new design). The commercial FEM (Finite Element Method) software was used for simulating the values of flow line, forging force and die stress, which were then used to determine part quality and tool life. The results have shown that the simulated values of 2-step design are similar to 3-step design. ฉ (2013) Trans Tech Publications, Switzerland.
