摘要: 摘要:为提高航空发动机第5级静子叶片的加工质量,对榫头现有的加工工艺进行了优化。结合传统静子叶片榫头加工方法,优化榫头加工工艺并进行金属切削实验,获得X、Y、Z三个方向力的数据。基于回归分析原理,求解出精加工刀具承受的最大切削力和表面粗糙度的经验公式,采用多目标优化方法得到刀具最优切削参数,并利用VERICUT对程序进行刀路、过切、碰撞检查,得到合理高效的加工方案。实验结果表明:采用改进后的榫头夹具和优化后的切削参数,叶片的加工效率得到明显提高并有效降低了刀具的磨损速度,使叶片榫头的加工工序从以前的45分钟缩短到现在的30分钟。研究方法及结论对航空发动机静子叶片的加工工艺优化具有重要的参考价值,同时也为叶身的后续精加工奠定了良好的基础。

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.
