METHOD AND SYSTEM OF TOP MACHINING Russian patent published in 2020 - IPC F01D11/14 B24B5/00 F01D25/28 

Abstract RU 2726303 C1

FIELD: machine building.

SUBSTANCE: method is provided for machining profile of vertex (512) of blade (130, 140) for turbomachine. Method comprises stages, at which blades (130, 140) are connected to turbomachine component (110, 112, 114, 120, 124); supporting component (110, 112, 114, 120, 124) on device (450) for machining, wherein device (450) for machining is configured to remove material from blade (130, 140) according to cutting path defined inside coordinate system of device (450) for machining, wherein component (110, 112, 114, 120, 124) is maintained such that base component (D) axial end surface (D) of component (110, 112, 114, 120, 124) matches base point (462) of device coordinate system (450) for machining; and blades (130, 140) are machined according to cutting path. Also, system is provided for machining profile of vertex (512) of blade (130, 140) for turbomachine.

EFFECT: improves accuracy and compatibility of gaps at blade top, especially for recessed blades.
