Cutting tool temperature distribution was mapped using the infrared-charge-coupled device technique during machining of carbon steel SS2511 (AISI 3115) and stainless steel AISI 316L under oblique cutting conditions with chip breaker geometry inserts. Results indicated that the temperature on the rake surface was not uniform. Local maximum temperature points are present on the tool face at different locations, i.e., land, groove, backwall, and at the end of tool chip contact. Further investigation of the effect of cutting parameters on the tool temperature indicated that a suitable combination of cutting speed and feed resulted in a lower tool temperature for conditions of comparable material removal rate.
