Abstract

Nickel based super alloys has high mechanical strength, resistance to corrosion and oxidation and high temperature strength. Research work on Alloy X-750 and Waspaloy has been infrequent due to difficulties in machining. The present investigation aims to analyze the tool wear, turning forces, and roughness in dry turning of Inconel X-750 and Waspaloy. The experiments are designed using the following parameters: speed = 50, 75, 100 m/min; rate of feed = 0.05, 0.075, 0.125 mm/rev. The depth of cut was kept at a constant value of 0.5 mm. PVD-coated carbide inserts are used for the turning operation, and the coating material was AlTiN. The cutting forces and surface roughness were measured post the tool wore out. The microstructures and Vickers’ hardness of the superalloys were also studied. Finally, the range of cutting conditions is recommended for machining this alloy in an industrial environment.
