ABSTRACT

In fastening applications, the majority of fasteners are produced by using the cold forming procedure. These fasteners are generally generated in multi-stage processes by cold forging, pressure forging, and reducing or a combination of all procedures. Cold forging, which is a type of metal forming process used in a broad spectrum of applications, from electronics to automotive and medical devices manufacturing, permits high-speed mass production with excellent mechanical properties in several applications. Engineering optimization is the matter which uses optimization techniques to obtain the best design and performance evaluation in engineering systems as quickly as possible. Simulation and optimization studies on the extrusion die geometry which is prepared for bolt production were carried out to investigate the effects of the input parameters on the extrusion force. The main aim is to provide the minimum extrusion force with valid optimum parameters in the extrusion die to form the workpiece.
