摘要
Slot milling is presented as a potential manufacturing route for aerospace component feature production when machining gamma-TiAl intermetallic alloy Ti-45Al-2Mn-2Nb + 0.8 vol.% TiB2XD using 2 mm diameter AlTiN coated WC ball nose end milling cutters. When operating with flood cutting fluid at v = 88 m/min, f = 0.05 mm/tooth, d = 0.2 mm, maximum flank wear was similar to 65 mu m after 25 min. SEM micrographs of slot surfaces show re-deposited/adhered and smeared workpiece material to a length of similar to 50 mu m. Brittle fracture of the slot edges was restricted to <10 mu m with sporadic top burr formation observed up to 20 mu m. Cross sectional micrographs of the slot sidewalls showed bending of the lamellae limited to within 5 mu m. (C) 2014 CIRP.
