摘　　要：延伸机匣是某航空发动机的重要承力部件,也是典型的对开机匣类零件,其壁厚较薄精度较高,通过一般的车、铣、钻孔等典型工艺进行加工后变形较大,部分尺寸和技术条件保证困难。在使用德马吉铣车复合加工中心的基础上,针对该延伸机匣的结构特点,研究了该工件的铣车加工工艺方法。通过合并传统加工工序并调整工序中车、铣和钻孔的加工顺序,从而达到缩短工艺路线、减小工件变形和提高工件加工质量的目的。The extending casing is a important force -bearing part on some aircraft engine, which is a typical half and half casing with thinner wall thickness and high precision. After machined by typical tech- nology of lathing, milling or drilling, it＇ s hard to guarantee the sizes and technology conditions be- cause of its large deformation. Based on using DMG turning milling compound maching center, ex- plores the turning milling process method in the light of its structure characteristics. The objective is to shorten the process line, reduces the parts deformation and improve the machining quality by mer- ging the machining process and adjustment the sequence of turning, milling and drilling in the process.
