鼓筒零件是由五级单盘焊接而成的转动部件，零件结构复杂，精度要求高，尤其是各级盘间内腔型面，属于全封闭深腔，空间狭窄，刀具强度低且干涉现象严重，按原工艺方法加工，切削时刀具振动产生的振纹现象严重，去除困难，影响零件交付工作。通过改进鼓筒零件内腔的刀具结构方案，优化刀具切削轨迹与加工参数，解决刀具在加工时的振动问题，提高内腔表面的加工质量，满足零件图纸需求，提升发动机制造的技术水平，实现了该项技术在生产中的工程化应用，取得了明显的技术效果和经济效益。

Rotating drum part is welded by ifve-stage single disc.The complex structure parts require highly precision machining, especially in the cavity be-tween the disc-to-disc surface, as the part is fully enclose deep cavity with narrow machining space left. Using the original method of machining processes,cutting tools chat-ter vibration and interaction are serious because of its low strength. The problem has affected the deliveries of the parts and hardly to avoid. By improving the structure of the cutting tool, the machining parameters and the cut-ting tool tracking are optimized which not only solves the vibration problems and improves the quality of cavity surface to meet the design requirements, but also enhances engine manufacturing technologies.
