The effect of machining factors on surface roughness and flank wear while turning steel alloy AISI 3415 using TiAlN coated carbide insert

Abstract

This research work is carried out to reveal the effect of turning factors such as cutting velocity, depth of cut and feed rate on the mean surface roughness and flank wear on turning cylindrical AISI 3415 steel alloy components. The experiments are designed based on (33) full factorial design and conducted on a turning centre (All Geared Lathe) with Titanium Aluminium Nitride (TiAlN) layered carbide tool of 0.8mm nose radius. The surface roughness of the turned steel alloy parts is deliberated by means of a precise surface roughness apparatus and the assessment of tool flank wear is measured by a toolmaker’s microscope with 30x intensification and 1µm resolution. A prediction model is created for mean surface roughness and flank wear by nonlinear regression examination with the aid of MINITAB numerical software.
