Abstract：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.
