Optimization Method of CNC Turning Parameters Based on Improved Gravity Search Algorithm
To improve the efficiency of CNC turning,optimize production quality,reduce tool wear and control production costs,a CNC turning parameter optimization method based on improved gravity search algorithm is proposed.Establish a turning parameter optimization model and determine the range of parame-ter optimization values through multi-objective constraint conditions.By using a multi-objective gravity search method,the position and mass of the central particle are determined,and the quality of the particle is measured.After iteration and convergence,the optimal solution is searched in space.Utilizing particle fit-ness function and introducing chaos idea to improve the algorithm for global optimization.Repeatedly infer the optimal position of particles under chaotic mapping to obtain the final optimal value of optimization pa-rameters.The experimental results show that the proposed method can effectively optimize parameters,re-duce production costs,and has good effectiveness and robustness.
