Evolutionary Computation in Combinatorial of Machining Parameters of Reinforced PEEK Composites Using NSGA-II

Article Preview

Abstract:

The machining parameters for turning of PEEK CF30 using TiN coated tools under dry conditions have been optimized by using Non dominated Sorting Genetic Algorithm (NSGA-II), a non dominated solution set is obtained. The objectives considered are the minimisation of machining force thereby minimising specific cutting pressure as function of the main operating parameters. The results indicated that the minimal cutting parameters are preferred for reducing the machining force, and the minimal cutting speed, medium depth of cut and high feed rate are recommended for minimal specific cutting machining. As per the requirement, the manufacturing engineer should select the proper cutting parameters.
