Description

technical field [0001] The invention relates to an ultrasonic cutting method for a honeycomb core boss structure, which belongs to the field of mechanical processing of honeycomb core materials. Background technique [0002] Honeycomb core materials have the advantages of high specific strength and specific stiffness, good insulation, corrosion resistance and light weight, and are widely used in aerospace, bioengineering, rail transportation and other fields. In industrial production applications, honeycomb core materials are often processed into various shapes. Traditional honeycomb processing adopts high-speed milling, and uses a special crushing milling cutter to crush and remove the honeycomb core material. However, during the high-speed milling process of the honeycomb core material, there are problems such as large deformation of the honeycomb core material, difficulty in ensuring the quality of the processed honeycomb, low cutting efficiency, serious tool wear, and s...

AI Technical Summary

Problems solved by technology

Using the traditional high-speed milling method, when the tool cuts into the workpiece at high speed, it is often accompanied by strong friction and extrusion between the tool and the material, resulting in burrs and crush defects in the honeycomb core material, affecting the processing quality and efficiency.

Compared with high-speed milling, ultrasonic cutting has significant advantages, but for the specific boss structure, due to its different processing mechanism and material removal method, the ultrasonic cutting process is quite different from high-speed traditional milling, and multiple ultrasonic cutting tools are required Coordination and cooperation can realize the processing of the boss structure
