The large-scale thin-wall skin self-adapting equal wall-thickness milling system comprises a contact probe, a contact probe signal receiver, a five-axes numerical control machine tool, a PC machine, a path measuring planner, a path measuring emulator, a curved surface reconstruction device, a thickness distribution fitter, a thickness compensation cutter track planner, a cutter track emulator and a supersonic wave thickness meter. In the invention, the surface morphology and thickness of a large-scale thin wall member can be respectively obtained through the contact probe and the supersonic wave thickness meter, an actual contour curved surface can be reconstructed by using a curved surface reconstruction device, then an actual thickness of the curved surface is calculated by using the thickness distribution fitter, the actual thickness and a theory thickness are compared through the thickness compensation planner, and then the thickness compensation cutter track can be obtained, so that purposes of higher automation degree and better processing precision can be reached.

Description

technical field [0001] The invention relates to a large-scale thin-walled part processing method, in particular to a large-scale thin-walled skin adaptive equal-wall-thickness milling system and a processing method thereof. Background technique [0002] The thickness reduction processing of large thin-walled parts has always been a difficult problem in processing and manufacturing. The existing processing methods are mainly divided into traditional milling and electrochemical milling. For these two types of milling processing methods, since the blank and the fitting surface of the fixture cannot be seamlessly fitted before processing, clamping errors will inevitably occur. During the processing, due to the deformation of the material by heat and force, the thin-walled material to be processed will produce elastic-plastic deformation, resulting in processing errors, and the precision machining of large thin-walled parts cannot be realized.
