An experimental investigation is presented involving radius end milling of a new nickel-based superalloy; Haynes 282. When operating with coated carbide inserts at high cutting speed and a feed rate of 0.1 mm/tooth, flank wear measured 213μm after 45 min of machining. Doubling the cutting speed or feed rate typically caused a pro rata reduction in tool life. The lowest operating parameters resulted in the best surface roughness with levels ranging 0.15–0.3μm Ra. Microhardness depth profile data was similar for all tests with a hardened region of up to ~50HK0.05 higher than the bulk value of ~480HK0.05, which extended to a depth of up to ~50μm from the workpiece surface. Surface/subsurface cross-sectional micrographs showed grain deformation/damage to a maximum depth of ~15μm.
