<div class="section abstract"><div class="htmlview paragraph">Aluminium alloys enrolled their applications in automobile sectors, agricultural
equipment, machine tools and aerospace because of their weight-to-strength
ratio. Aluminium alloy 7075-T651 is an inevitable material used in engineering
sectors. Turning is a metal removal process, to obtain net geometrical aspects
and better surface finish of the products. The machinability of the turning
operation is based on different factors; however, turning factors and material
of tool plays a significant position in the turning process. To identify the
truthful cutting parameters to achieve multi-responses in turning operation, the
experiment was designed via Response Surface Methodology (RSM) Central Composite
Design (CCD) and the experimental results are analyzed under the desirability
approach. By trialing 26 interpretations in the desirability approach; the
optimal cutting parameter settings of speed 800 rpm, feed rate 0.140315 mm/rev
and depth of cut 0.3501 mm have been revealed to enhance surface roughness (SR)
and metal removal rate (MRR).The confirmation test addresses better agreement
with the predicted value of responses, the result of the investigation directed
to the industries for the variant aluminium alloy parts manufacturing.</div></div>
