The traditional turning process has used in this study to develop a mathematical model from experimental data to predict the surface roughness of titanium chrome-molybdenum (Ti-Cr-Mo) alloy when the workpiece is machined with cutting parameters i.e. spindle rotational speed, feed rate and depth of cut. In order to determine the contribution of the cutting parameters, the analysis of variance (ANOVA) has been applied and Taguchi technique (smaller the better) has been used to optimize the parameters that affect the surface roughness. Mitutoyo SJ-400 roughness tester with cutoff length 0.8 mm has been used to measure the surface roughness of machined workpieces. Optimal parameters that are obtained to achieve minimum surface roughness value are 280 rpm rotational speed, 0.5mm/rev feed rate and 0.59 mm depth of cut.

Abstract


The traditional turning process has used in this study to develop a mathematical model from experimental data to predict the surface roughness of titanium chrome-molybdenum (Ti-Cr-Mo) alloy when the workpiece is machined with cutting parameters i.e. spindle rotational speed, feed rate and depth of cut. In order to determine the contribution of the cutting parameters, the analysis of variance (ANOVA) has been applied and Taguchi technique (smaller the better) has been used to optimize the parameters that affect the surface roughness. Mitutoyo SJ-400 roughness tester with cutoff length 0.8 mm has been used to measure the surface roughness of machined workpieces. Optimal parameters that are obtained to achieve minimum surface roughness value are 280 rpm rotational speed, 0.5mm/rev feed rate and 0.59 mm depth of cut.
