Study of Cutting Tool Durability at a Short-Term Discontinuous Turning Test
The article deals with study of cutting performance and its impact on durability of cutting tool in a short-term alternate turning test. The short-time test was carried out at discontinuous machining to increase an intensity of tool wear and to reduce the time of the test. Two types of workpieces in shape of circular segments with angles of 45° and 180° were prepared from material DIN 17200 that correspond to the STN 41 1373 (11 373) steel. Cutting plates, type of SPUN 120504, from the 19 830 steels with the tool holder type of CSSPR 2525 M12 KT 716 were used at the machining. The tests were realized based on the standard ISO 3685 without cutting fluid. The process of machining and tool wear was evaluated from the energy point of view. The machine input power was measured by means of measuring equipment UNI-T UT232. The results were statistically processed. Based on the results it can be said that the durability of tools at the machining the 45° segment was higher. Also, the hypothesis considering that the work of cutting wedge is constant during machining up to the achievement of critical tool has not been confirmed.
