The aircraft large-scale aluminum alloy integral wall panel has several characteristics such as thin walls

weak rigidity

and difficult locating and clamping during the CNC machining. It is difficult to ensure wall thickness and weight tolerance. It is a typical type of difficult-to-machining aircraft structure parts. This paper studies the high-speed milling technologies dealing with aircraft large-scale aluminum alloy integral wall panel

analyzes the structure characteristics of the panel

designs the fabrication order and programming strategy about the panels and supporting embosses in the rough machining operations

uses the vacuum fixture

adjusts the dimension of thickness and takes two times finish machining by the adaptive machining method of the measurement and adjustment integrated

which can keep the thickness and weight tolerance effectively.
