Corner numerical control processing automatic programming method for aircraft complicated structural component

Abstract

The invention discloses a corner numerical control processing automatic programming method for an aircraft complicated structural component, which comprises the steps of 1) side steering plane calculation; 2) cutting element calculation; 3) interference domain construction; 4) residual domain calculation; and 5) processing unit construction. Therefore, automatic programming of a corner processing numerical control program can be realized. According to the corner numerical control processing automatic programming method, the programming personnel need not to carry out tedious interactive operations or complicated geometric parameter calculation, programming for the corner processing numerical control program can be completed by only interactively selecting any one corner plane, and problems of low or unstable program quality and the like caused by a practice that technicists carry out programming interactively in a mode of relying on experience are effectively avoided. The corner numerical control processing automatic programming method can significantly improve the efficiency and the quality of corner processing, shorten the product development period and improve the market competitiveness of products.

Description

technical field [0001] The invention relates to the field of numerical control machining and manufacturing of aircraft complex structural parts in aviation manufacturing, in particular, an automatic programming method for corner numerical control machining of aircraft complex structural parts. Background technique [0002] In modern aircraft design, in order to meet the requirements of high performance, integral structural parts with superior performance are widely used, such as integral structures such as wall panels, beams, frames and wing ribs. In order to meet the structural weight design requirements, there are a large number of cavity structures in the overall structural part. The corner is an important sub-feature of the cavity structure, and its processing efficiency and quality directly affect the processing efficiency and quality of the part. The overall structural parts have the characteristics of complex structure, high processing precision requirements, and high...
