Optimization of the Effect of Cutting Parameters on the Cutting Force in the Gradual Turning Process by Taguchi Method

Abstract

In this experimental study, AISI 4140 steel was subjected to machining experiments on the CNC lathe. The effect of cutting forces (radial force (Fx), tangential force (Fy) and feed force (Fz)) depending on the cutting parameters were investigated experimentally. As cutting parameters, three different cutting speeds (V) (100 m min-1, 140 m min-1 and 180 m min-1), feed rates (f) (0.08 mm rev-1, 0.12 mm rev-1 and 0.16 mm rev-1) and cutting depths (a) (0.5 mm, 0.9 mm and 1.3 mm) were preferred. The experimental design was made according to the Taguchi L9 vertical array. The effects of cutting parameters on cutting forces and contribution rates were analyzed by analysis of variance (ANOVA). The effect levels of cutting parameters on cutting forces were determined using the S/N ratio. Optimum cutting parameters are defined. After ANOVA analysis, it was determined that the feed rate was effective on the radial force and tangential force, while the depth of cut was effective on the feed force. According to the verification experiments, it was seen that the optimization was successfully applied.
