Experimental, Numerical and Statistical Investigation of Cutting Force in the Machining of AISI H13 Hot Work Tool Steel

Abstract

In this study, the effects of cutting parameters on cutting force are investigated in turning of AISI H13 hot work tool steel with ceramic cutting tools. Turning experiments have been performed at three different cutting speeds (180 and 240 m min-1), three different feed rates (0.12, 0.15 and 0.18 mm rev-1) and three different depths of cut (0.6, 1 and 1, 4 mm) on a CNC lathe under dry cutting conditions. At the same time, turning simulations have been made with Third Wave AdvantEdge software based on finite element analysis (FEA). The cutting force data obtained by experimental and numerical analyzes have been also statistically analyzed using the Taguchi method, Anova, and regression analysis. The analysis results revealed that the most effective parameter on the main cutting force (Fc) values obtained by both methods was the depth of cut with the contribution rates of 80.97% and 80.32%, respectively. Moreover, an average of 9% difference was obtained between the main cutting force values (Fc) obtained in the turning simulations and experimentally and the optimum parameter group for the Fc values obtained by both methods were A3B1C1 (cutting speed = 240 m min-1, feed rate = 0.12 mm rev-1, and depth of cut = 0.6 mm).
