High-Pressure Cooling in Finishing Turning of Haynes 282 Using Carbide Tools: Haynes 282 and Inconel 718 Comparison

Despite the interest of industry in nickel-based superalloys and its main features (high temperatures resistance, hardness, low thermal conductivity, among others), even today they are still materials that difficult to cut. Cutting tools withstand both high pressures highly localized at cutting area because elevated work hardening alloy problems for fluid access region, with consequent strong tool wear. The use fluids improves coolant heat removal. This paper analyzed machining Haynes 282 by means coated carbide under high-pressure finishing conditions. Tests were developed different speeds feeds quantifying forces, surface roughness, wear, life. Values 45.9 min Ra between 2 µm 1 obtained this study life respectively, combination speed 50 m/min feed 0.1 mm/rev. Likewise, a comparative analysis is included results previous works authors relating turning Inconel 718 conventional pressure cooling. due importance within nickel base being widely used scientific literature.
