摘要: 飞机舱门属于典型的飞机薄壁零件，其加工质量直接影响飞机的装配精度和使用性能，本文对某型飞机舱门类的薄壁腔体难加工零件进行了加工工艺分析和流程定制设计，对切削刀具的切削原理进行分析并选型，利用VERICUT软件优化切削参数，对刀具轨迹和程序进行了优化。研究发现用优化应力释放槽的工件，尺寸精度能够满足设计要求。优化后的程序有效地提高了加工效率，为提升航空结构件的加工精度提供了实践参考。

Abstract: The aircraft door is a typical thin-walled part of an airplane, and its machining quality directly affects the assembly accuracy and performance of the aircraft. This paper conducts an analysis of the machining process and customized design of the workflow for a difficult-to-machine thin-walled cavity part of a certain type of aircraft door. It also analyzes the cutting principles of cutting tools and selects appropriate types, optimizes cutting parameters using VERICUT software, and refines the tool paths and programs. The study finds that workpieces with optimized stress-relief grooves meet the dimensional accuracy requirements. The optimized program effectively improves machining efficiency, providing practical reference for enhancing the machining precision of aerospace structural components.
