چکیده مقاله
In bulk metal forming processes, the coulomb friction law and the shear friction law are used traditionally In this study, isothermal closed die forging process of alloy AA7075 was simulated using finite volume method to investigate the effect of friction conditions on workpiece temperature The results show that at different condition of shear friction coefficients, throughout the process, the model has approximately the same workpiece temperature value It is also concluded that at different condition of friction coefficient until 94% of the process, the coulomb friction model represents a larger workpiece temperature; afterwards the shear friction model represents the larger values increasingly
