Abstract

Globally manufacturers are stressed to simultaneously fulfil the need for higher productivity, economy, better surface integrity and green manufacturing. Hence keeping a broad view of above needs, this paper investigates the surface residual stresses in high-speed turning of Inconel 718 by using PVD coated carbide cutting tools at an optimal cutting speed, feed and depth of cut under completely eco-friendly machining environments viz. dry, water vapour and chilled air. Additionally, the emphasis has been also given on understanding the efficacy of methods of supplying the eco-friendly cutting fluids through the external nozzle as well as internally through tool holder. Results reveal that usage of water vapour leads to better surface integrity in terms of advantageous compressive residual stresses and also further leads to cleaner machining. Further supplying the cutting fluid internally through tool holder than externally through the nozzle is much beneficial in lowering the tensile residual stresses.
