2 Abstract Turning operations were performed on multiple specimens of both steel and aluminum round bar stock. The intended purpose of machining these samples was to obtain data for an analysis of the factors affecting the surface finish of machined materials. These factors include tool condition, material feed rate and tool radius. The analysis also examines the difference between ideal and actual surface roughness, resultant chip thickness ratios, and tool wear due to feed rates. From the results of the analysis, it can be shown that the primary controllable factors which govern the relative magnitude of surface finish are tool radius, feed rates, and tool condition. To enhance the surface finish of a work piece material, the feed rate should be relatively low, a large tool radius should be selected, and conditions should be set to maximize a specific tool condition life.
