Abstract

The invention relates to an automatic high-precision edge milling device and method for an aircraft skin. Point position alignment, normal leveling, flexible clamping, trajectory planning of a milling cutter, numerical control code generation and other functions on a region to be milled are achieved in an automatic control mode, and accordingly the size precision, normal precision and notch roughness of the skin are guaranteed.

Description

technical field [0001] The invention belongs to the field of automatic edge milling of aircraft skins, and specifically refers to an automatic high-precision edge milling and modification system suitable for aircraft skins. Background technique [0002] Skin automatic edge milling technology is a technology based on product digital design and manufacturing, and it is also one of the most advanced processing technologies in aviation manufacturing. It relies on high-precision edge milling equipment, multi-degree-of-freedom machine tool systems and advanced automatic control technology , to ensure that the milling accuracy of the aircraft skin is controlled within the allowable range of error, thus making precision manufacturing and assembly possible. [0003] Due to the characteristics of large size and low rigidity of the aircraft skin, especially in the docking stage, the connection with the stringers, enclosures and other parts has been completed, resulting in poor mobility...
