The typical parts of an aircraft that require machining in aircraft manufacture consist primarily of aircraft fuselage structural components and engine critical components. Typical parts of an aircraft fuselage structure include, among others, beams, ribs, frames, panels, connectors, sliding rails, etc.

Under the background of the vigorous development of aviation industry, the requirements on the dimensional accuracy and the surface quality of parts are higher and higher, and if some defects such as burrs and the like occur after the parts are machined, the parts are not allowed to be manually removed, and the parts need to be milled by programmed software control. According to different materials, the aviation parts can be processed by adopting metal materials (stainless steel, magnesium alloy, titanium alloy, aluminum alloy, structural steel, high-temperature alloy and the like) and non-metal materials (aviation ceramics, special rubber, carbon fiber and the like).

Titanium alloy, stainless steel, aluminum alloy and various composite materials are widely used for manufacturing fuselage reinforcing frames, wing spars and reinforcing ribs, and are used for achieving the purpose of reducing weight while enhancing the strength of aviation parts.
