Abstract:

Determination of the maximum temperature during machining process and its distribution along the rake surface is important as it influences the tool life as well as the quality of machined part. In this paper a model has been developed for the prediction of temperature distribution induced in Whisker Reinforced Ceramic insert in finish orthogonal turning of Inconel 718 using ANSYS. The power consumed in metal cutting during turning operation is largely converted into heat. Therefore, transient state machining operation in orthogonal cutting is studied by modeling the heat transfer between the tool and chip at the tool rake surface contact zone. A hybrid approach combining experimental results of cutting and feed forces in turning of inconel 718 has been applied for development of this finite element method based model.
