The present study is concentrated with orthogonal cutting of AISI 1040 carbon steel under dry turning conditions with PVD coated cemented carbide inserts. This paper presents the influence of cutting parameters on the surface roughness of carbon steels of AISI 1040 series. The investigations are carried out by conducting experiments based on Taguchi technique considering L27 orthogonal array. The investigations consists of surface roughness of the material under hot and cold conditions, this aspect is studied due to variation of temperature during turning process showing the affects of online monitoring of tool surface roughness. The other general investigations are signal to noise ratio and analysis of variance are employed to the parameters such as Material removal Rate (MRR). Finally, sensitivity analysis is carried out on most influenced cutting parameter to predict the surface roughness by obtaining the absolute fraction of variance.
