Abstract :In this study, the effects of the parameters of cutting speed, feed rate and minimum quantity lubrication insert ignore into journalissuearticles values(MQL); frequently employed in machining applications on main cutting force insert ignore into journalissuearticles values(Fc); and surface roughness insert ignore into journalissuearticles values(Ra); were investigated. For this purpose, analyses for Fc and Ra were performed utilizing Box-Behnken model. The efficiency of parameters and the changes in parameters on Fc and Ra were studied with the help of experiment set composed of 13 experiments by employing experimental parameters. Also, the effectiveness of design models was investigated by creating different design models. The high success rate modelling for Fc and Ra was realized with 99% success as a result of analyses conducted according to Box-Behnken and Stepwise, Backward and Forward methods of Box-Behnken. The most effective parameter among experimental parameters on Fc and Ra was found to be the feed rate according to Variance Analysis insert ignore into journalissuearticles values(ANOVA);. It was demonstrated that the estimations on the created Box-Behnken model were quite successful on the data initially entered into the system; and that R2 values obtained for Fc and Ra were 0.999 and 0.996, respectively. It was determined that optimum parameters for the Fc were feed rate 0.25 mm/rev, cutting speed 125 m/min and cutting condition MQL2 ml/min, while they were feed rate 0.25 mm/rev, cutting speed 125 m/min and cutting condition MQL1 ml/min for Ra.
