Meanwhile, experiments of high-speed orthogonal cutting are performed to verify the simulation results with cutting speeds ranging from 50 m/min to 7000 m/min. High-speed steel tools should be used for interrupted cuts such as occur in the roughing of an uneven surface. Meanwhil The main challenges to machining superalloys include: The high strength of nickel-base superalloys at cutting temperatures causes high cutting forces, generates more heat at the tool tip (compared to alloy steel The harder the material, the slower the cutting speed should be.
