| Popis: | In this research work, a new incremental slab method analysis has been derived to calculate extrusion force and its die pressure distribution during an extrusion process, while a die of arbitrary shape is used. In addition, a computational algorithm has been presented based on the proposed analysis method and Archard’s wear model to investigate the effect of die profile on its working life. Three different die profiles including optimum curved, optimum constant angle, and cylindrical shaped are numerically evaluated. The results revealed that the predicted extrusion loads and die pressure distributions through the implementation of the applied method are in an acceptable agreement with FEM analysis results. Moreover, it has been demonstrated that the maximum wear depth on all die profiles is located at the die exit area, which indicates the predominant effect of the material velocity profile. It is also found that the die life of the two optimum dies would be the same, but the least working life estimated is the working lifetime of the cylindrical die profile. |
