AI Technical Summary

Problems solved by technology

If the paste strength is not enough, the tool will partially lift the honeycomb core parts during the CNC machining process, resulting in inaccurate profiles after machining
If the adhesive strength is too strong, it will make it difficult to remove the processed honeycomb core part from the processing platform, and even tear the processed chamfered part

Embodiment 1

[0022] Step 1, melting of the low-melting-point filler: select a low-melting-point alloy with a melting point of 70°C, and melt it by heating;

[0023] Step 2, filling of the honeycomb core grid: after the 70°C melting point alloy is melted, put the paper honeycomb core to be processed into it until the surface to be processed is submerged, and press the briquetting block on the upper surface of the paper honeycomb core;

[0024] Step 3, solidification of the filler: lower the temperature below the melting point of the filler, so that the 70°C melting point alloy filler is solidified in the paper honeycomb core grid, and then take out the paper honeycomb core;

[0025] Step 4, fixing and processing of the honeycomb core: use double-sided adhesive tape to fix the filled and solidified paper honeycomb core on the processing platform for CNC machining, and remove the honeycomb core parts after completion;

[0026] Step 5, taking out the filler: Put the removed paper honeycomb cor...

Abstract

The invention belongs to the field of digital processing, and relates to a honeycombed-core type surface numerical control processing method. The method comprises the following steps: step one, low-melting-point fillers are molten; step two, honeycombed-core lattices are filled; step three, the fillers are solidified; step four, a honeycombed core is fixed and processed; and step five, the fillers are taken out. The low-melting-point fillers are used so that the shape of the honeycombed core can be solidified, and a requirement for processing a concave surface of a honeycombed-core component can be solved by using ordinary processing cutting tools. After the low-melting-point fillers are used, bonding intensity between the honeycombed core and a processing platform is increased and the edge of the honeycombed-core component is not liable to be damaged so that processing efficiency and processing quality of the honeycombed-core type surface are enhanced by the method.

Description

technical field [0001] The invention belongs to the field of digital processing, and relates to a numerical control processing method for a honeycomb core profile. Background technique [0002] Numerical control of honeycomb core is very common in the field of composite material manufacturing, but in the process of processing, problems such as unstable positioning and inadequate processing of complex profiles often occur. At present, the cutting tool for CNC machining of honeycomb core parts is usually a disc type. The cutting tool of this shape can meet the processing requirements when processing the plane shape, convex shape and guide groove of the honeycomb core part, but when the upper and lower profiles of the honeycomb core part have concave , this tool cannot meet the processing requirements of the honeycomb core part profile. Moreover, at present, double-sided adhesive tape is used to paste the honeycomb to be processed on the processing platform during CNC machinin...
