Abstract

The advantages of today’s cold forging technology, such as excellent mechanical properties of the workpiece and minimum waste of material together with energy saving via near net shaping increase its competitiveness against other production methods. However, as a result of extremely high loading of the tools when compared with warm and hot forging, tool life is distinctly more confined resulting in increased production costs. Due to separately or concurrently emerging damaging mechanisms of fatigue and wear at different sections of a cold forging die, process specific tool material selection and design of cold forging dies play a decisive role in near-net-shape forging of various parts. Two case studies utilizing powder metallurgical tool steel and ceramic as tool materials are presented in this paper. Successful adaptation of these materials with the help of FE simulations led to increased tool life and workpiece quality.
