Abstract:Abstract: In order to improve the machining quality of the aeroengine’s level five stator blade, this paper optimized the existing machining technology. Combined with the traditional machining method of stator blade tenon, optimized the machining technology of tenon and made metal cutting experiment, got the data with X,Y,Z three directional force. Based on the Regression analysis theory, solved the bearable maximal cutting force of the finishing tool and the experience formula of surface roughness, by used multi-objective optimization methods got the optimal cutting parameters on tool, and made use of VERICUT to check the tool path, overcut, collision of the program, at last got an reasonable and efficient machining scheme. The experimental results showed that used the improved tenon fixture and the optimized cutting parameters, significantly improved the machining efficiency of the blade and effectively reduced the tool wear rate, and made the blade tenon machining operations from the previous 45 minutes to 30 minutes now. The research methods and conclusions has important reference value to the aeroengine stator blade machining process optimization, it as well as laid a good foundation to the leaf blade’s subsequent finishing machining.
