초록

The purpose of this study is to design the free forging tool for the high accuracy of the thrust shaft in marine engine. In order to do it, the principal factor controlling the uprightness of the flange part and the excessive margin and folding in middle part of thrust shaft after forging process was identified using FEA. Based on the results, the optimum shape of free forging tool and working method were proposed and verified through the mock-up and the actual product test.
