Abstract
High-efficiency deep grinding experiments of nickel-based superalloy Inconel718 were conducted with a vitrified cubic boron nitride wheel. An investigation was made to detect the relationship between the undeformed chip thickness and grinding temperature and burn-out behavior of the workpiece material. The results display that the grinding forces and grinding power increase with the increase of the undeformed chip thickness. When the coolant is in the nucleate boiling state, the grinding temperature keeps stably at below 140 °C; however, the grinding temperature increases rapidly to the materials burn-out point once the coolant enters the film boiling state. The critical range, 0.65 ∼ 0.75 μm, is determined for the undeformed chip thickness under the defined experimental condition, which could take a great effect on controlling the grinding burn-out and increasing the grinding efficiency.
