Cutting Temperature in Machining of TI-6AL-4V Alloy and Its Predictive Model

Titanium alloy (Ti-6Al-4V) is a biomaterial which has an incomparable weight-strength ratio, corrosion resistance, and thermal resistance than any other commonly used metals. It is one of the reasons for using it in implants, aerospace, defense applications. The induced cutting temperature during machining is higher as it is one of the hard materials. It is chemically active, and it tends to react with tool material. But it must be confronted as it has wide industrial applications. This research was intended to investigate the cutting temperature during turning of Ti alloy and analyze the significance of cutting parameters such as cutting speed, feed rate, and depth of cut. The Taguchi L27 orthogonal array was utilized in conducting experiments. The range of parameters and their effect on cutting temperature were statistically analyzed. At this end, a predictive model using ANFIS was developed and validated. Performance metric RMSE was found to be very minimal (9.31994e-05).
