Abstract: |
Taking a head supporting device used for aerospace engine as an example, the deep pores that the length to diameter ratio is 30 times efficient machining technology is studied based on the material characteristics and cutting performance of Ti2AlNb alloys. The suitable cutting tool and cutting parameters are given, and a set of suitable method is summarized for Ti2AlNb alloys deep pores efficient cutting based on different cutting tools and its cutting parameters on cutting test. A train of thought is provided for high efficient cutting technology research of TiAl base class of lightweight difficult-to-cut alloys. |
