Abstract

In this study, CNC turning process parameters are optimized while machining AA6061 – T6 alloy. The process variables, namely, cutting spindle speed or spindle velocity (Cs), rate of feed (Fr), rate of the depth of cut (Dc), and nose radius (Nr), were optimized with output responses such as surface roughness (Ra), feed power (Fx), thrust power (Fy), cutting power (Fz), and removal rate of material (MRR). The optimized results showed higher MRR, Fy, and Fz and lower Fx and Ra were obtained at a cutting spindle speed or spindle velocity (Cs) of 100 rev/min, rate of feed (Fr) of 0.2 mm/min, depth of cut (Dc) of 1.5 mm/min, and nose radius (Nr) of 0.8 mm. TOPSIS and ANOVA were used to assess the experimental results to determine the most favourable factors that were superior and suitable for selecting the optimal variable condition.

Keywords: AA6061-T6 alloy, ANOVA, CNC Turning, Cutting power, Depth of the cut, Feed power, Material removal rate, Multiresponse Optimization, Nose radius, Rate of feed, Spindle Speed, Surface roughness, Thrust power, TOPSIS.

INTRODUCTION

Aluminium is ductile and has an FCC (Face Centred Cubic) structure. Al is a lighter metal with 2900 kg/m³ as density. It has higher electrical and thermal conductivity due to its lower density. Various wrought aluminium products include mechanical finishes, chemical finishes, and coatings.

Mechanical finishes include cold finished, buffed, and textured coatings, whereas chemical finishes include etched, bright dipped, and chemical conversion coatings. Anodizing, painting, plating, and chemical conversion coatings are included in the coating category. Due to low density to high strength ratio, toughness, and corrosion resistance, aluminium alloys are mainly used in automobiles and aerospace Industries. Zn, Si, Mg, Cu, are major alloying elements that are classified into cast-based alloys and wrought-based alloys with heat-treatable and non-heat-treatable properties.

Chemical composition of AA6061-T6 (T6- heat-treated, rapid cooling and aged) is Al - 97.25%; Cu - 0.32%; Mg - 1.08%; Mn - 0.52%; V - 0.01%; Fe - 0.17%;Sic - 0.63%; Ti - 0.02%, which is a work-hardened alloy with a low density to high strength ratio, increased hardness, improved toughness, capability of welding, and greater resistance to corrosion. The strain hardening method is highly effective in improving the strength of materials.
