Effect of machining parameters on surface roughness in end milling of AISI 1019 steel

Abstract

This article presents experimental investigation on AISI 1019 steel for study of surface roughness in end milling operation using carbide inserts. The objective of this work is to establish the empirical relationships between the machining parameters and average surface roughness using response surface methodology. The first-order and quadratic models have been developed in terms of feed, cutting speed, depth of cut, and nose radius. Furthermore, the Box–Cox transformation has been employed to improve the prediction ability of the first-order model. The cutting speed, feed, and nose radius seem to have the significant effect on surface roughness.
