This study is an attempt to investigate the influence of cutting tool geometry on the surface texture of a turned cylindrical component. Centre lathes with carbide cutting tools of varying radii were used to turn the carbon steel component. Various feeds and cutting tool approach angles were used during the turning operation while Talysurf measuring instrument was used to measure the centre line average (CLA) surface roughness. Data obtained from the experiment was analysed theoretically coupled with the usage of SPSS software (version) 22.0 to obtain the mathematical relationship between the surface roughness of tool nose radius and approach angle of a cutting tool. The result showed that with constant speed and cut, surface roughness decreased when using larger tool nose radius. Based on the findings, it is recommended that tool with large nose radius and minimum approach angle should be used when finishing the turning of carbon steel.
