Embodiment Construction

[0023] A multi-layer splicing preformed honeycomb numerical control machining method is provided. The method uses a five-coordinate high-speed machining center machine tool and a honeycomb numerical control machining tool in a closed space. The tool is a crushed combined modeling honeycomb milling cutter of cemented carbide material. Described processing method comprises the following steps:

[0024] Step 1, processing the multi-layer spliced ​​preformed honeycomb core block so that the edge wheel of the core block protrudes twice the thickness relative to the middle profile of the core block;

[0025] Step 2, opening positioning holes on both ends of the longest diagonal line of the honeycomb core block; the aperture of one of the positioning holes is compatible with the positioning pin of the machine tool, and the aperture of the other positioning hole is twice the diameter of the positioning pin of the machine tool;

[0026] Step 3. Set a 3 mm thick fiber cloth on the botto...
