Machining Aerospace Materials

Abstract The aerospace industry is driving the use of advanced materials such as titanium and heat‐resistant nickel alloys and composites, and demand for large monolithic parts. The desirable properties of these materials also make them difficult to machine, presenting problems such as rapid tool wear and chatter. This chapter surveys the problems of machining these difficult‐to‐cut aerospace materials, with a focus on titanium alloys. Cutting theory is introduced, and common problems and their causes are explained. The mechanisms of tool wear and failure are examined. The chapter outlines machining strategies to avoid these problems, with consideration of a range of tool and cutting parameters.
