Abstract: In order to select optimum cutting parameters, an optimization framework of cutting parameters based on Genetic Algorithm (GA) was constructed. Issues relevant to GA were also discussed in detail. Based on the mathematic models of constraints and single-objective functions, multi objective function was built by using the method of linear weighting addition. The constraints were expressed in objective function by formulating them as penalty functions so that the seeking process was simplified and sped up. An optimizer of cutting parameters based on GA was developed to optimize the cutting parameters and utilized to analyze the effects of constraints on the optimization results of cutting parameters in turning. Finally, constraints effects on optimization results of cutting parameters were concluded.
