The Analysis of Four-Axis Belt Grinding for Marine Propeller Blade
Marine propeller blade is composite of the free form surface, its machining method has been a difficult thing. The blade is processed by 4-axis belt grinding machine in this experiment, this paper analyze that the wear of the abrasive belt and the processing precision and the material removal rate of the blade according to the grinding performance of the blade material, the structural features of the vane, and the theory of 4-aixs belt grinding machine. Draw formulas with time for the belt wear height and the actual grinding depth. The life expectancy of the ceramic abrasive belt is the longest, and its the material removal rate is maximum in Three kinds of belt,and when the belt line speed is 30m/s or so, the material removal rate is maximum.
