Sažetak

The paper presents the results and the influence a single factor has in the drilling process. The research is focused on how modifying the cutting speed influences parameters like cutting forces, cutting temperature, tool life, wear mechanism, and chip formation. For this experiment three different cutting speeds have been tested on high-speed adapted twisted drill geometry, each of them corresponding to a certain cutting domain: 200 m/min, 165 m/min and 110 m/min. The temperature, predicted with finite element simulation (FEM), forces, wear evolution and the shape of chips have been analysed in order to prove if high speed adapted drill geometry can be used instead of an ordinary drill while performing at lower speeds. The tests certified the ability of a drill designed for high speed to process in conditions associated with lower cutting speeds, behaving similarly in all the cases.
