Optimization of cutting parameters using Response Surface Method for minimizing energy consumption and maximizing cutting quality in turning of AISI 6061 T6 aluminum

Feed rate and depth of cut were the most significant factors for minimizing the total specific energy consumed, and for minimizing the surface roughness, feed rate was the most significant factor. Compared to the traditional objective optimization, the optimal turning parameters determined by the proposed optimization method reduced the energy consumption in 14.41%, and the surface roughness in 360.47%. Consequently, sustainability and quality of the machining process were achieved at the same time.
