With the development of modern aviation technology, higher requirements are put forward on the stealth performance of an aviation aircraft, and a large amount of novel high-performance materials are introduced. The cellular wave-absorbing material is widely applied to a new generation of combat aircrafts by virtue of the advantages of stealth capability, high strength-to-weight ratio and the like which are one of the most important technical characteristics. However, the honeycomb wave-absorbing material has poor cutting processing performance, and particularly, the honeycomb wave-absorbing material is subjected to deep cavity numerical control processing. In the prior art, the cutting processing of the honeycomb wave-absorbing material is essentially different from the cutting processing of metal parts, the cutting chips generated by the cutting edge of the honeycomb wave-absorbing material are not generated by shearing like most metals, but are broken to remove the redundant wave-absorbing material, and the method mainly comprises the processing of profiles and contours.
The existing processing of the honeycomb wave-absorbing material has the following problems: (1) the processing depth of the material cannot be too large, otherwise, the phenomenon that the cut honeycomb damages the uncut honeycomb easily occurs, and finally, the special tool for the existing honeycomb wave-absorbing material is low in cutting rate and poor in quality, and dust-shaped cuttings are adhered to the tool; (2) the secondary cutting of the chips and the honeycomb material can cause the cutting temperature to rise, and the processing quality of the honeycomb material is influenced; (3) because the honeycomb material is strictly forbidden to contact with liquid such as water, oil and the like, cutting fluid cannot be used in the honeycomb processing process, powdery cutting chips adhered to a cutter are difficult to remove in a traditional mode, and the requirement of high-quality and high-efficiency milling processing of a deep cavity of a honeycomb wave-absorbing material part is difficult to meet; (4) due to the characteristics of the material, the quality problems of over-cutting, milling damage, tearing, deformation, more burrs and the like are easily generated in the deep cavity processing process, so that the yield of parts is low, and the processing efficiency is low.
