Face milled surface roughness as a result of changing the feed rate and the chip size ratio using rectangular insert

Abstract

Surface quality affect the fit, the lifetime and the performance requirements of parts and structural units. Thus, we must plan the expected surface roughness. Due to the characteristic kinematics of face milling, the roughness of the surface is inhomogeneous, which means different roughness in different directions measured on the surface. We examined the effect of the change of feed rate on the surface roughness in this article since increasing feed rate is an effective way to increase productivity.
