Abstract

The term machinability refers to the ease with which a metal can be machined to an acceptance surface finish. The factors that typically improve a material’s performance often degrade its machinability. Therefore, to manufacture components economically, engineers are challenged to find ways to improve machinability without harming performance. Surface finish is an important parameter in manufacturing engineering. It is a characteristic that can influence the performance of mechanical parts and production costs. The investigation of influence of cutting conditions in turning of Duplex Stainless Steel 2205 is made in this project. The experimental design was formed based on Taguchi’s technique. An orthogonal array and analysis of variance (ANNOVA) are employed to investigate the turning conditions and machining was done using CVD triangular carbide insert. The objective was to establish correlation between cutting speed, feed rate and depth of cut and optimize the turning conditions based on surface roughness. These correlations are obtained by multiple regression analysis.
