Abstract :
Surface roughness is one of the determinant factors that govern the quality of machined surfaces. This paper experimentally studies effect of machining parameters on surface roughness (R ) for end milling of AISI 1045 workpiece using a TiAlN coated carbide milling a cutter. Taguchi optimization method has been used to determine the optimal level of three control factors, namely, feed rate, spindle speed and depth of cut. Analysis of variance (ANOVA) demonstrates that the feed rate is the most significant parameter and contributes 47% for surface roughness. Finally, the contour plots of these three parameters have been analysed to determine the optimal ranges of control factors.
