Summary:Cylindricity tolerenace is one of the critical requirement of precision axisymmnetric components for their assembly and functional requirements. Genetic algorithm (GA), a heuristic approach is proposed in this paper to find optimum minimum cylindricity form tolereance parameter. The objective function for cylindricity has been statistically modelled using face centered central composite design (FCCCD) which works based on response surface methodology. Each term used in model are highly significant with 95% of confidence interval. The analysis shows cylindricity is highly affected by feed rate with 14% contribution followed by depth of cut 6% and tool nose radius 3.5%. There are significant interact of cutting speed with depth of cut, and feed rate with depth of cut and tool nose radius.
