Optimization of Cutting Insert Geometric Parameters based on Entropy-weighting TOPSIS
摘要
Abstract
In order to solve the multi-objective optimization problem of cutting insert geometric parameters and avoid the unsatisfactory processing effect in turning,an optimization decision method based on entropy-weight Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) was proposed.By using TOPSIS model and finite element method,and considering the results such as wear depth,cutting force,tool-chip interface temperature and tool-chip interface pressure,the controllable factors of cutting insert shapes,relief angle,nose radius were planned for orthogonal experiment design,and the objective values were received by numerical analysis.Due to the determination of entropy weight coefficient,a weighted normalized matrix of multi-objective optimization was built.The distance between experiment design sequence and ideal solution was calculated to get relative approach degrees,and the existing schemes were ordered.According to the effects of each factor on the results,the optimal geometry parameter combination was determined.On this basis,the geometric parameters of cemented carbide inserts are provided by engineering practice and the results shows that the proposed method is valid and feasible.关键词
