Validation and optimization of cutting parameters for Ti-6Al-4V turning operation using DEFORM 3D simulations and Taguchi method

In this study, we show that optimising cutting forces as a machining response gave the most favourable conditions for turning of Ti-6Al-4V alloy. Using combination computational methods involving DEFORM simulations, Taguchi Design Experiment (DOE) and analysis variance (ANOVA), it was possible to minimise typical such force, power chip-tool interface temperature. The parameters were varied in study include speed, depth cut feed rate. optimum parameter combinations would responses established by using “smaller better” criterion selecting highest value Signal Noise Ratio. Confirmatory simulation revealed speed 120 m/min, 0.25 mm 0.1 mm/rev rate, lowest force 88.21 N temperature 387.24 °C can be obtained. Regression indicated correlation coefficient 0.97 obtained between parameters. relationship linear since first-order regression model sufficient.
