| Abstract: | The authors have experimentally clarified the influence of the tool wear on the tool fracture probability in the finish turning of hardened steels of various hardness values using a tool with a round cutting insert of cBN/Si3N4 composite. The maximum stresses and fracture probability have been determined for the tool face and flank. Recommendations regarding the use of cBN/Si3N4-inserted cutting tools are provided. |
