Abstract :This study focused on the Grey-Based Fuzzy Logic Algorithm for the prediction and optimization of multiple performance characteristics of oblique turning process. Experiments have been constructed according to Taguchi’s L16 orthogonal array design matrix. Cutting speed, rate of feed and depth of cut were selected as input parameters, whereas material removal rate, cutting force and surface roughness were selected as output responses. Using grey relation analysis insert ignore into journalissuearticles values(GRA);, grey relational coefficient insert ignore into journalissuearticles values(GRC); and grey relation grade insert ignore into journalissuearticles values(GRG); were obtained. Then, Grey based fuzzy algorithm was applied to obtain grey fuzzy reasoning grade insert ignore into journalissuearticles values(GFRG);. Analysis of variance insert ignore into journalissuearticles values(ANOVA); carried out to find the significance and contribution of parameters on multiple performance characteristics. Finally, confirmation test was applied at the optimum level of GFRG to validate the results. The results also show the application feasibility of the grey based fuzzy algorithm for continuous improvement in product quality in complex manufacturing processes.
