Analysis and Modeling of Thrust Force by using Response Surface Methodology in Drilling Nanocomposite

Abstract

In this study, the effects of drilling parameters on the thrust force in the drilling process of glass fiber reinforced polymer composites were investigated experimentally and statistically. Multiwalled carbon nanotube wt. % content, cutting speed and feed rate were considered as independent variables, the thrust force was considered as dependent variable. Experiments are conducted based on Box–Behnken design. A mathematical model was developed to predict thrust force using response surface methodology. Desirability Function Analysis was used to determine optimum drilling parameters. The influence of process parameters on the thrust force has been evaluated using analysis of variance. The results indicate that the feed rate is the most significant design factor influencing the thrust force. The values predicted from the model and experimental values were found to be very close to each other.
