Now a days research over improvement of surface finish on mechanical elements has become quite significant in the operational and aesthetical point of view. As a consequence, to enhance accuracy and precision, manufacturing firms are adopting, the automated systems in order to achieve manufacturing excellence.In the present work the effect of various process parameters like speed, feed and depth of cut on the surface finish in end milling process is investigated by using standard statistical tool i.e., Factorial Technique.The coefficients are calculated by using regression analysis and the model is constructed.Further,it is tested for its adequacy by using fisher’s test.By using the mathematical model the main and interaction effect of various process parameters on surface finish is studied.The developed model helps in selection of proper mathematical tool and machining parameters for a specific material and also helps in achieving the desired surface finish.
Key words: End Milling, Surface Finish, Factorial Technique.
