Abstract :In this paper, the effects of the different cutting parameters on the surface roughness in turning AZ31 magnesium alloys were investigated. Three cutting parameters, such as depth of cut insert ignore into journalissuearticles values(t);, feed rate insert ignore into journalissuearticles values(f); and cutting speed insert ignore into journalissuearticles values(V);, were used in the turning operation. Experiments were designed for L9 Taguchi’s model. Tests were performed on a CNC lathe. The surface roughness values were measured in the tests. Taguchi and ANOVA analysis were evaluated to detect main effect parameters and their contribution ratios. The optimum cutting parameters for the surface roughness were computed as “t” at level 2 insert ignore into journalissuearticles values(2 mm);, “f” at level 1 insert ignore into journalissuearticles values(0.2 mm/rev); and “V” at level 1 insert ignore into journalissuearticles values(320 m/min);. Moreover, empirical equations were developed by using regression analysis insert ignore into journalissuearticles values(RA); to predict the surface roughness and compared to experimental results.
