Keywords : Surface roughness, Dry machining, Cermer cutting tool Abstract :Abstract— Coatings over the cutting tools are very much useful for enhancing their performance in high-speed machining such as CNC Dry turning. Automobile industries use a number of coated tools for producing the various parts. However, problem of quality and economical production still occurs during the high-speed machining of hard materials. In the present experimentation, the comparison of the performance of multi-layer coated and single coated, uncoated cermet tools has been studied during the dry turning of EN8 Steel. A comparison between the performance of uncoated, single coated and multilayer coated tools has been made using cutting parameters (speed, feed and doc) by using the Surface roughness as the output parameters. Surface roughness was also lower for multilayer coated tool.The final surface finish obtained with the multilayer coated inserts was 1.51 times the surface finish with single coated inserts and 1.40 times when compared with uncoated inserts
