Abstract
Manufacturers worldwide embark for higher productivity and this can be ensured through high-speed machining (HSM). Additionally, the vigorous governmental pollution control norms have urged for cleaner manufacturing techniques. Hence considering the above, this paper relatively investigates the chip formation aspects in high-speed turning of Inconel 718 by using PVD coated carbide cutting tools at constant machining parameters under perfect eco-friendly machining environments viz. dry, water vapour and chilled air. The chip formation aspects have been mainly explored through chip deformation coefficient which aids in identifying the lubrication status for the specific machining environments. Further emphasis has been also given on understanding the potency of methods of delivering the eco-friendly cutting fluids through external nozzle or through internal channel special tool holder. Results show that use of water vapour as a cutting fluid in machining comparatively gives lower chip deformation coefficient and hence proves to be an eco-friendly solution. Additionally the cutting fluid supply through internal channel special tool holder is found to be advantageous than external nozzle supply due to the better cutting fluid delivery and interaction with machining zone. Further combination of both, water vapour as cutting fluid and its supply through internal channel special tool holder, still further relatively gives excellent results in terms of lower chip deformation coefficient. Thus usage of the same can be a well suitable approach towards green manufacturing.
