Abstract: In machining, surface integrity of product is of major concern and crucial to some of the functional properties of the component in service. This work investigated the effect of cutting parameters on surface roughness of AISI 1020 mild steel on lathe turning in dry condition. An indexable titanium nitride (TiN) coated carbide tool insert mounted on a general multipurpose Widax tool holder was used for the turning. The parameters considered were cutting speed, feed rate and depth of cut while Taguchi method and analysis of variance were used to support the investigation. The result indicated that high cutting speed, low depth of cut and low feed rate are required for low surface roughness. A third order regression model was able to predict the surface roughness of AISI 1020 steel based on the parameter ranges employed with the presence of significant process parameter interactions and the coefficient of determination, R2, of the model was obtained as 0.96.
