Tool-chip interface temperature is analyzed experimentally during turning of 4140 steel alloy and Inconel 718 with tungsten carbide tools using a tool-work thermocouple technique. The experimental results are compared with Loewen and Shaw’s analytical results. Based on the experimental results, an empirical model relating the tool face temperature to cutting conditions is established for 4140 steel alloys with tungsten carbide tools. Finally, the tool-chip interface is investigated with flank and crater wear to determine the effect of tool face temperature on these tool wear mechanisms.
