Deep drawing process,one of sheet metal forming methods,is very useful in industrial field because of its efficiency.The deep drawing process is affected by many material and process parameters,such as the strain-hardening exponent,plastic strain ratio,anisotropic property of blank,friction and lubrication,blank holder force,presence of drawbeads,the profile radius of die and punch,etc.In this paper,a finite element method is used to investigate the cylindrical deep drawing process.The thickness of product and the forming force predicted by current simulation are compared with the experimental data.A finite element method is also used to investigate the maximum forming load and minimum thickness of products under various process parameter conditions,including the profile radius of die,the clearance between die cavity and punch and the blank holding force.Furthermore,the material anisotropy and process parameters effect on the earing are also investigated.
