A Study on Predictin of Die Life of Warm Forging by Wear(II) -Application of Suggested Die Wear Model-

마멸에 의한 온간단조의 금형수명 예측에 관한 연구(II) -금형 마멸 모델의 적용-

In bulk metal forming processes prediction of tool life is very important for saving production cost and achieving good material properties. Generally the service life of tools in metal forming process is limited to a large extent by wear, fracture and plastic deformation of tools. In case of hot and warm forging processes, tool life depends on wear over 70%. In this study finite element analyses are applied to warm forging and hot forging by adopting suggested wear model. By comparision of simulation and real profile of die, suggested model is verified
