Optimization of Machining Parameters in Hard Turning of SKD61 Steel by Using Taguchi Method

This research focuses on building a mathematical model of cutting parameters including cutting speed, feed rate, and depth of cut in turning SKD61 steel. Taguchi method was applied to create experimental index. Signal to noise ratios and analysis of variance analyzed the significance of each value. The result showed that the feed rate parameter has the most effect on the roughness of the cutting piece, following by the cutting speed and the depth of cut respectively. The built model was success to predict the surface roughness with R sq of 90.85 .
