Tool orientation planning for minimizing surface error in five-axis machining of copper alloy

摘要

Five-axis machining is increasingly applied in manufacturing complicated parts, such as blade of numerous-blade propeller rotor and compressor impeller, benefit from providing enough accessible space of the tool orientation. Then it becomes more important and difficult of tool orientation planning because of more requirements and higher demands. Main purpose of this paper was just to propose a method, which served for tool orientation planning considering the effect of cutting force induced surface error in five-axis machining of copper alloy. Geometric relationship of cutter and workpiece was analysed firstly. Then the proposed tool orientation planning method was described, followed by building the mathematical model. Finally, the effectiveness of the planning methods was verified by experiment of machining a proportionally reduced ten-blade propeller rotor.
