摘要：

One of the most used forming processes for series production is the cutting of metal sheets. The tensional behavior of the cutting tools is an extremely important issue in the aforementioned process. In this research, using the Finite Element Method, the cutting of 16 mm diameter holes in 2 mm thick plates is simulated. Geometric parameters of the cutting punch are analyzed, such as: the variation of geometry of agreement radius and eccentricity between Punch Symmetry Line (PSL) and Shear Force of Gravity Center (SFGC), to determine their influence in the stress state of said tool. It is evident that the use of the Bezier radius in metal cutting punches guarantees a resistive reserve over punches with circumferential radius. There is an increase in the stress value as the eccentricity between the PSL and the SFGC increases; finally, the influence of this geometric condition on the stress behavior of metal cutting punch is related in a mathematical model, also taking into account the geometric typology of agreement radius.
