A Review of Effects of Temperature Distribution on Tool Life in Turning Process by using Finite Element Analysis

Temperature on the chip-tool interface is important parameters in the analysis and control of machining process. Due to the high shear and friction energies dissipated during a machining operation the temperature in the primary and secondary shear zones are usually very high, hence affect the shear deformation and tool wear. This paper is a review of research work in last decade on temperature distribution in turning process. Research is going on to investigate the level of maximum temperature generated at tool rake face and to control this temperature thereby improving the tool life and quality of work piece. In this study, the temperature generated on rake face of cutting tool and experimental methods for measurement of temperature are reviewed. Out of number of interface temperature measuring methods, the special attention has been paid to the tool work thermocouple as it is easy to apply and inexpensive as compared to other techniques. The procedure for the working of tool work thermocouple and the method of calibration is described in this paper. The calibration set up establishes the relationship between emf developed and the cutting temperature. To compare and validate the experimental results, the FEA model is the best way and also it helps to locate the highly temperature affected area on the tool insert.
