Patent application number 201210024096.6 discloses an ultrasonic vibration cutting device, which is mainly composed of cutting blade, cutting tool head, lock nut, horn, and fixed chuck. The intermittent contact of the workpiece and chips reduces heat generation and cutting force, but it is not possible to select appropriate cutting process parameters such as edge inclination angle, leading angle, and rake angle according to different materials and working conditions to facilitate the process. cutting

In the patent application number 201821763680.2, a new type of bending-torsional composite vibration ultrasonic cutting device is disclosed. This device can also solve the problem of high-precision machining of certain mechanical parts in aerospace. The device proposes a single-directional vibration In actual machining, there is high-frequency friction between the flank of the tool and the machined surface of the workpiece, and the tool is subject to constantly changing alternating tension and compression stress during the cutting process, and the tool is prone to fatigue and chipping. Therefore, the compound vibration machining technology was studied. , can change the harmful friction between the rake face of the tool and the chip into a favorable cutting force, reduce the cutting temperature and cutting force, and improve the machining accuracy, but the operation of the equipment is complicated
