Abstract

The objective of this research work is to find the optimal set of process parameters to produce better quality products for pneumatic piston rod application through turning operation. The control factors considered for the study are spindle speed (N), feed rate (f), depth of cut (d) and tool nose radius (r), and the experiments are planned based on Taguchi's L9(34) orthogonal array. The experiments were conducted in a CNC (Computer Numerical Control) turning centre using CNMG TiN coated carbide cutting tool insert of three different nose radius, such as 0.4 mm, 0.8 mm, and 1.2 mm, on AISI 1040 medium carbon steel. The optimal combination of control factors and the corresponding levels were determined for the minimum surface roughness based on signal to noise ratio using MINITAB statistical software and simultaneously, a mathematical model was developed for the surface roughness through regression analysis. The confirmation result revealed the effectiveness of Taguchi's technique by providing better quality product.
