The invention provides a molding method for specially-shaped chamfer of the tooth type of a movable vane, relates to the technical field of a vane manufacturing process and solves the technical problem about difficult molding of low-edge tooth. The molding method comprises a formation method of a basic model, an original positioning surface, a low-side tooth characteristic line, a low-side tooth machining surface and an overall machining surface, as well as a manufacturing method of the specially-shaped chamfer of the tooth type of the movable vane. The molding method provided by the inventionis used for improving the machining process of the specially-shaped chamfer of the tooth type of the movable vane so as to meet the requirement of people that the connection of an axial-flow compressor and a TRT vane root satisfies the designed standard strength.
