Özet
In this study, the effects of cutting speed, feed rate and minimum quantity
lubrication (MQL), frequently employed in machining applications, on main
cutting force (Fc) and average surface roughness (Ra), resulting from
turning AISI 4140, were investigated. For this purpose, analyses for Fc and
Ra were performed utilizing Box-Behnken model. By using experimental
parameters, the efficiency and the changes of the parameters on Fc and Ra
were examined with the help of 13 experiments. In addition, 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 methods (BoxBehnken, Box-Behnken-Stepwise, Box-Behnken-Backward and BoxBehnken-Forward). The most effective parameter on Fc and Ra was found to
be the feed rate according to analysis of variance (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 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.
