Experimental Study of Cutting Forces in Ball End Milling of Al2014-T6 Using Response Surface Methodology

In the present research, the influence of cutting parameters (cutting speed, feed per tooth, axial depth of cut and radial depth of cut) during ball-end milling of Al2014-T6 under dry condition has been studied. The experimental plan was based on face centred, rotary central composite design (RCCD). Three cutting force components i.e. tangential, radial and axial forces were measured and then analysis of variance (ANOVA) is performed. It has been found that the quadratic model is best fitted for prediction of the force components. The analysis of result shows that the cutting forces increases as increase in feed per tooth and axial depth of cut but decreases with increase in cutting speed. Radial depth of cut has significant effect on the cutting force components.
