摘　　要：高速加工具有生产效率高、加工精度高、表面质量好和生产成本低等优点。在现代航空产品中,高速加工已广泛应用于飞机的梁、框和大型壁板等承力构件。由于航空制造业中主承力结构件多数为整体坯料"掏空"的整体结构件,因此,在材料去除率大、加工质量要求高、加工周期长的整体结构件的加工中更能体现其独特的优势。但是,其转角的加工还延用传统加工方式。本文通过实例,对高速切削零件转角加工技术提出了全新的加工方案,为航空壁板类及墙类零件的高速加工提供了实践基础。High speeding machining（HSM） has the advantages such as high production efficiency, machining accuracy, surface quality and low production costs. Among modern aviation products, HSM has been widely applied to the load carrying structures such as beam, frame and large wallboard etc. In aviation industry, main load-carrying structures are mostly whole blank ＂hollow＂ structures. Therefore, they show the advantages of higher elimination percentage of materials, higher machining quality demand, and longer machining terms in whole structure machining, but the machining of corners are still at the tradilional stage. Through examples, the paper proposed a brand new machining proposal for high speed cutting parts corner machining technology, which pro vided practical basis for the high speed machining for aviation wallboard type and wall type parts.
