Abstract
This study assesses the sustainable subtractive manufacturing of Wire Arc Additive Manufactured (WAAMed) Inconel 625 (IN625). Compared to other additive manufacturing techniques, WAAM is economically efficient and has a higher deposition rate. However, post-subtractive manufacturing operations are often required for additive manufactured (AMed) parts to make them ready for industrial applications. Drilling trials were conducted on AMed and wrought IN625 under three environments: dry, flood and cryogenic. Their machinability was evaluated in terms of cutting forces, torque, power consumption as well as surface roughness. Also, the surface morphology of drill tools, drilled holes and machined chips were analysed and compared. Results show that the cryogenic environment enhances tool life and surface integrity for drilling of WAAMed parts, whereas flood environment emerged as a better cooling/lubricating condition for machining wrought specimens.
