ANALYSIS OF SURFACE ROUGHNESS AND MATERIAL REMOVAL RATE IN DRY AND THERMAL ASSISTED MACHINING OF EN8 STEEL
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 3
Abstract
It is widely understood that aerospace materials such as titanium, nickel based alloys and high strength steels are difficult to machine owing to their favorable material properties. An alternative pathway to achieving greater tool life is thermally assisted machining (TAM). This approach is seemingly contradictory to the traditional method and instead relies on introducing heat from an external source to reduce the work piece material’s strength and hardness, thereby reducing cutting forces and making the material easer to machine. In present research to investigate experimentally the role of thermal assisted machining on various parameters at recommended speed, feed and depth of cut, and to compare the effectiveness of dry machining with thermal assisted machining on EN-8 steel. The objective of present work is concluded and recorded that is Surface roughness has been decreased in thermal assisted machining significantly, due to the ease in machining by application of heat. Heat softens the material and helps in easy removal of the material resulting material removal rates increase significantly
