| description | Turbine blade root are commonly processed by grinding, and the grinding process parameters determine the surface quality and fatigue performance.The effect and mechanism of grinding parameters are investigated on the surface roughness and hardness of third generation nickel-based single crystal super-alloy DD9 based on orthogonal experiment.The experimental results show that grinding surface roughness is mostly affected by the wheel speed <i>v</i><sub>s</sub>, followed by the workpiece feed <i>v</i><sub>w</sub>, the grinding depth <i>a</i><sub>p</sub> is few effects on the grinding surface roughness.The machining hardening is appeared at the grinding surface for grinding DD9, the hardening degree is ranged from 1.9% to 13.8%, and the depths of hardening layer are between 60 and 120 μm.In order to obtain a surface with small surface roughness, uniform texture and small degree of hardening in grinding DD9 super-alloy, a grinding parameter scope is recommended as, <i>v</i><sub>s</sub>∈[20 m/s,25 m/s], <i>v</i><sub>w</sub>∈[12 m/min,16 m/mim], <i>a</i><sub>p</sub>∈[10 μm,15 μm]. |
