Green Machining and Forming by the use of Surface coated tools

In metal cutting industries cutting fluids are widely used to obtain longer tool life and better surface finish of the component. In metal forming industries oil based lubricants are used to control friction, reduce die wear and thereby increase the surface quality of the component. The cutting fluids and lubricants used in metal cutting and forming industries represent 16 -20% of the manufacturing costs and have several negative health and environmental impact. Green or dry machining is desirable for a clean, safe and cost effective process with high quality products. In this paper, the performance evaluation of poly crystalline cubic boron nitride cutting tool towards the goal of dry machining is presented.
