Problems solved by technology

[0002] Honeycomb core material is widely used in the aerospace field due to its advanced performance, but in the cutting process, due to the characteristics of easy deformation and weak rigidity in the plane of the honeycomb core material, and there is no good clamping method that can reliably fix the honeycomb core material. The core material is clamped, so the cutting quality of the honeycomb core material is generally poor

Abstract

The invention provides a honeycomb core material optimization cutting processing method. The method comprises the steps of obtaining typical machining defects of a honeycomb core material through honeycomb core material milling tests and representing the defects at the cut-in angles of the honeycomb walls where the defects obtained through classification and detection are located; establishing a relation model, namely an optimization condition equation of cutting parameters and the value taking interval of the cutting parameters, between the cutting parameters and the cut-in angles, and selecting the cutting parameters according to the value taking interval so as to achieve optimization cutting processing of the honeycomb core material. Through the honeycomb core material optimization cutting processing method, the manufacturing defects of the honeycomb core material are avoided, and the high-quality processed surfaces are obtained.

Description

technical field [0001] The invention relates to a technology in the field of mechanical processing, in particular to a method for classifying defects occurring in the processing of honeycomb core materials and a method for characterization of their locations, and a low-defect processing technology optimization method for all defects. Background technique [0002] Honeycomb core material is widely used in the aerospace field due to its advanced performance, but in the cutting process, due to the characteristics of easy deformation and weak rigidity in the plane of the honeycomb core material, and there is no good clamping method that can reliably fix the honeycomb core material. The core material is clamped, so the cutting quality of the honeycomb core material is generally poor. The thickness of the honeycomb wall itself is only tens of microns, and it is easy to produce various defects under the action of cutting force, including but not limited to processing burrs, collaps...
