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 milling of aircraft skins, and specifically refers to an automatic high-precision milling and shaping system suitable for aircraft skins. Background technique [0002] Automatic skin milling technology is a technology based on product digital design and manufacturing, and it is also one of the most advanced processing technologies in aerospace manufacturing. It uses high-precision 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 tolerance range, so that precision manufacturing and assembly are possible. [0003] Because the aircraft skin has the characteristics of large size and low rigidity, especially in the docking stage, the connection with the long stringer, the enclosure frame and other parts has been completed, resulting in poor mobility of the entire structure, and...
