Opis:: 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.

Opis:: Guards on machine tools are meant to protect operators from injuries caused by tools, workpieces, and fragments hurled out of the machine's working zone. This article presents the impact resistance requirements, which guards according to European safety standards for machine tools must satisfy. Based upon these standards the impact resistance of different guard materials was determined using cylindrical steel projectiles. Polycarbonate proves to be a suitable material for vision panels because of its high energy absorption capacity. The impact resistance of 8-mm thick polycarbonate is roughly equal to that of a 3-mm thick steel sheet Fe P01. The limited ageing stability, however, makes it necessary to protect poycarbonate against cooling lubricants by means of additional panes on both sides.
