Abstract:
This paper presents the research and analysis of tool wear in turning of hardened bearing steel 100Cr6 using carbide tools. Machining of the mentioned steel is almost impossible using standard machining conditions and uses of carbide cutting tools. In this study, cutting process is carried out using HPJAM dosing technique in which a jet of cooling and lubrication fluid, under high pressure (50 MPa), leads to the zone between the cutting tool edge and workpiece. Experimental measurements were performed for different input process parameters. Process of cutting tool wear is analyzed by monitoring of width of flank wear on carbide tool inserts.
