Abstract As one of the key components of the assembly camshaft， the manufacturing method of cam has a great influence on the development of camshaft and engine. The numerical simulation of compacting and hot forging process was validated by comparing density distribution of simulation and experiment. Then， the method of numerical simulation was used to improve and optimize the process parameters for the compaction and hot forging process of the cam. For compacting process， the density distributions of green compact under different compacting methods (single compaction， double compaction， floating compaction and friction compaction) was simulated. For hot forging process， the density distributions of forged piece with different combinations of five primary parameters， which are forging speed， friction coefficient， heating temperature of compact， preheating temperature of mold， initial relative density of compact was studied.

Key words： metallic materials powder forming process numerical simulation cam relative density
