Abstract This work aims to analytically and numerically material and the friction between the work-piece material study the parameters affecting on the wire drawing process and the die-interfaces to estimate the necessary force to carry using a 3D finite element model and the effect of these out the process, by different methods. Wire drawing and parameters on drawing force. Three-dimensional finite plate drawing have been modeled and simulated by means of element model using DEFORM-3D V6.1 was built to the slab method (SM) and finite element method (FEM). The simulate this process. AL-1100 wire was drawn through a solutions comparison confirms that FEM is a more accurate conical die with semi-die angle ( 伪 = 6掳 , 8掳 , 8.5掳 , 9掳 , 9.5掳 , method than SM because the obtained results with it are 10掳,, 15掳 ), reduction ratio ( r = 0.1 , 0.15 , 0.2 , 0.25 , 0.3), nearer to the real results. FEM provides very intuitive friction coefficient ( 碌 = 0.1 , 0.08 , 0.075 , 0.07 , 0.065 , 0.06 , simulations in which the forward tension can be seen not 0.05), bearing length ( BL= 0.5 , 0.75 , 1 , 1.25 , 1.6 ) mm,
