This invention provides a multi-energy field assisted ultrasonic cutting device and method for CFRP preforms, relating to the fields of intelligent manufacturing and precision machining technology. The invention uses a laser generator to precisely and locally heat the cutting area, softening the resin matrix in the processing area and significantly reducing the material's strength and cutting resistance. Simultaneously, eddy current tubes cool the non-cutting areas of the workpiece, enhancing the stiffness of the resin matrix in these areas and the constraint force on the carbon fibers, effectively suppressing excessive deformation and displacement of the carbon fibers during processing. Ultrasonic vibration further induces brittle fracture of the carbon fibers through high-frequency impact, reducing the tensile effect caused by resin viscosity. Ultimately, this achieves the beneficial effects of high-quality, high-efficiency, and low-damage processing of CFRP preforms.
