Modeling and optimization of finish diamond turning of spherical surfaces based on response surface methodology and cuckoo search algorithm

Surface roughness is one of the most significant factors to indicate product quality. Diamond turning an efficient and highly accurate material removal process improve surface quality workpiece. In present study, arithmetic mean absolute (Ra) total height profile (Rt) spherical during finish a commercial brass alloy CuZn40Pb2 were modeled using Response Methodology (RSM). The experimental investigations carried out Central Composite Design (CCD) under dry conditions. effect cutting parameters such as spindle speed, feed rate depth cut) on was analyzed analysis variance (ANOVA). A cuckoo search (CS) algorithm used determine optimum machining minimize roughness. Finally, confirmation experiments verify adequacy considered optimization algorithm.
