Description

Technical Field

[0001] The invention belongs to the field of honeycomb core material machining, and relates to a planar honeycomb sinking milling control device and method. Background Art

[0002] like Figure 1 As shown, honeycomb core materials are widely used in the manufacture of structural components for aviation and spacecraft. Various shapes of parts often need to be embedded and assembled inside them. Therefore, a portion of the honeycomb is cut out on the honeycomb surface to create a depression of the corresponding shape.

[0003] At present, the CNC milling method is generally used for honeycomb sink processing. Production practice shows that CNC machining has the advantages of high processing surface precision and good surface quality, but it also has the following disadvantages: 1. Since the honeycomb core is a regular hexagonal cell panel formed by bonding and stretching aramid paper or metal foil, the honeycomb panel has low rigidity and is easily deformed by its own weight. When the deformation is large, the honeycomb core is prone to damage such as node debonding and cell wall creases. 2. Since CNC machining requires a positioning reference and the honeycomb core is prone to deformation, auxiliary positioning such as positioning tooling is required, which increases the manufacturing cost; 3. The honeycomb core undergoes processes such as clamping and disassembly and is extremely susceptible to mechanical damage. Summary of the Invention
