Study on Mechanical Processing of the Harvester Blade Based on Fuzzy Multi-criteria Algorithm
摘要
Abstract
The stirred dragon blade is a complex surface mechanical parts, the mechanical processing is a complex multi element composite process. In order to improve mixing dragon blade machining accuracy of it proposed a blade machining based on CAD software and Pro/E to go tool path simulation optimization method. The method used CAD extraction stirred dragon blade surface as the key point,which in stired dragon blade surface data point extraction process. And it produced the processing a large number of control points. In order to optimize the control points,it proposed a fuzzy multi criteria al-gorithm to realize the blade machining decision and optimization of transformation from experience to theory guidance. In Pro/E software, key points of the extracted modeling, it obtained the blade surface, shape by merging the dragon blade curved surface solid mixing. Finally, the entity of trajectory simulation tool has been stirred the machining accuracy of the dragon blade, and it compared a fuzzy multi criteria algorithm and non fuzzy multi criteria algorithm under the control of the machining accuracy. By the comparison results, it show that fuzzy multi criteria algorithm can effectively improve the harvester blended with the machining accuracy of the dragon blade.关键词
