Research on Key Technology of CNC Abrasive Belt Grinding for Aircraft Engines Blade Edges
摘要
Abstract
In order to improve the machining accuracy and efficiency of the leading and the trailing edges (LTE) of aircraft engines blade,the existing problems in grinding of the current aircraft engines blade edges were analyzed,combined with the current requirements of machining technology for LTE and the motion control algorithms of computer numerical control(CNC) belt grinding machine,considering the influence of the grinding elements such as particle size,contact force,belt speed and feed rate,the tool trajectories are optimized,a grinding technology of the blade edges is put forward.Finally,the aircraft engines blades were subjected to actual grinding experiments.The experimental results show that the grinding method can obviously improve the machining precision and the surface roughness of the blade.关键词
