Abstract The design error values of severd design methods according to the design formula of PM cylindrical compaction mold was calculated，and tried to reduce the errors by combining the different design methods. At last an optimized design method with no（zero）design error was obtained. This paper realized the precise design of the tooth profiles of powder metallurgy gear molds，and provided a feasible method for the precise design of PM gear formation mold.

Key words： gear tooth profile design comprehensive size change rate design error precise design
