According to the system and the method, the skin is subjected to roll-bending forming, is flattened, is subjected to vacuumizing adsorption through the vacuum adsorption platform and then is subjected to material thickness machining through the numerically-controlled machining equipment, so that the manufacturing accuracy of parts is improved, the surface quality of the parts is improved, the machining efficiency is improved, and the environment is protected.

Description

technical field [0001] The invention relates to a numerical control machining system and method, in particular, the invention relates to a skin numerical control machining system and a method thereof. Background technique [0002] After the skin parts are formed, the chemical milling process is used for subsequent processing in aircraft skin processing. Although this process can better solve the processing problems of complex concave cavities / concave surfaces, it has chemical pollution, high power consumption, and the consumption of aluminum cannot be recycled, and the chemical milling method after the skin parts are formed has problems in part manufacturing accuracy. Inherent disadvantages such as low machining efficiency and low processing efficiency have plagued the aviation industry. Or some enterprises use the thickness of the material to be machined in the flat state of the skin parts, and then rolled and formed. The thickness of the material is machined in the flat ...

AI Technical Summary

Problems solved by technology

The method provided by this invention patent is to carry out CNC milling first, and then perform bending forming. However, the aforementioned problems still cannot be solved: during the roll forming process, a depression occurs at the root of the machining milling area and stress concentration is likely to occur, which affects the parts. Surface quality, stress concentration at the root of the machining milling area affects the fatigue life of the part

And the chemical milling method will pollute the environment and increase the treatment cost
