Experimental investigation of different cutting conditions in turning of Inconel 718

It is a known fact that large amount of heat is generated between tool and work piece during machining process. Coolant is used to enhance the cutting conditions and traditional one is
hydrocarbon oil based. This will result in deteriorating the operator’s health and environmental imbalance [1]. Some other alternative methods are also available such as dry machining, Minimum Quantity Lubrication (MQL), vegetable oil as cutting fluid, cryogenically treated tool and solid lubricants. Few drawbacks with alternative methods namely, dry machining affects metallurgical changes and releases more heat, vegetable oil depends on its properties, Cryogenic treatment and
MQL method need special equipment [2-4].One among the simplest and safest substitute to conventional cutting fluid is solid lubrication. In order to reduce the friction coefficient and
contribute to sustainability in machining, texturing on cutting tool is used. As solid lubricant is applied on the textured tool a noticeable reduction in cutting zone temperature, friction and
machining forces is observed because a continuous solid lubricant film is produced on tool. This is due to the thermal expansion of heat produced during machining [5].Various types of solid lubricants are explored by different researchers [6-9].
