Investigations on dry and wet EN-24 steel turning through CNC machine.

When it comes to meet removal techniques, the process of turning holds paramount significance in the contemporary times. To improve the working of cutting tools at the time of operating various machining such as MMC machining and high speed machining, hard coating and cutting fluids are consider to be essential and healthy. The quality and the budget of production has got immensely affected by the development of tool used for cutting and high speed machining for hard materials. The working of multi-layer coated carbide tools while experiencing different cutting conditions of EN-24 has been included in the present work. Tool wear measurements demonstrate that Multilayer Coated carbide under wet cutting conditions offer a reasonable tool life. Surface Roughness was also found better for carbide inserts for wet conditions. The final surface appearance acquired through the multilayer carbide inserts/tools for wet conditions remained 0.224 times the surface finish achieved through the carbide tools without using lubricants. Wear rate of multilayer carbide inserts has been decreased through 0.994 times under wet conditions. MRR for multilayer coated ceramic inserts in case of dry cutting conditions was found 0.754 times the MRR of carbide inserts under wet conditions. It has also been found that the turning of rigid material is upgraded by using multilayer coated carbide inserts in the wet environment when compared to that of dry cutting conditions.
