In this study, a numerical model of the shearing process was developed using the finite element method and the effect of the main process parameter - clearance between tools on the deformation of DC01 steel and quality of the sheared edge was analyzed. The shearing process was considered a geometrical and physical nonlinear problem with unknown boundary conditions in the contact area of the system, such as the tool and workpiece. Numerical results were obtained based on slitting process using the dynamic explicit method in the ANSYS/LS-DYNA code. Experimental verification was conducted to confirm the results of the finite element simulation. These experimental results showed good agreement with those of the finite element simulation. Obtained results can be used to select the optimal clearance in shearing and decrease the scrap.
