Broaching is a high_precision, high_efficiency and complicated machining way that can generate final shape, and it is used widely in aerospace engine manufacturing to machine spline ways for plate_type components and cogs for vanes. The text describes in detail the broaching process way, discusses the basic principle for high_speed broaching, analyzes comprehensively the factors influencing the surface quality and durability & service life of broaches, compares the conventional and high_speed broaching process, demonstrates the advanced features of high_speed broaching process. The text takes spline ways of typical plate components as example, studies the dimensional requirement and features for broaching for longitudinal spline ways, and makes up advanced and reasonable broaching parameters, programs and broach design.
