Investigations on Effect of Cutting Forces and Surface Finish in Plain Milling Using Box Behnken Design

Abstract

Nowadays research over improvement of machining process as a part of it cutting forces and surface finish on mechanical elements has become quite significant in the operational and aesthetical point of view. To enhance accuracy and precision, manufacturing firms are adopting automated systems in order to achieve manufacturing excellence. In the present work, the effect of various process parameters like spindle speed, feed, and depth of cut on the cutting forces and surface finish in plain milling process is investigated by using Box Behnken Design. Three factors- three levels are used and total 15 experiments are performed. The coefficients are calculated by using regression analysis and the model is constructed. The adequacy of the developed model is checked using Analysis of Variance (ANOVA) technique. By using the mathematical model the main and interaction effect of various process parameters on cutting forces and surface finish are studied.
