Abstract: Disclosed is an ultrasonic cutting method employing a straight-blade sharp knife. The ultrasonic cutting method employing the straight-blade sharp knife includes the following steps: S1, measuring parameters of the straight-blade sharp knife; S2, initially rotating, by the straight-blade sharp knife, around an axis thereof, such that a rear knife surface of the straight-blade sharp knife is attached to or is away from a machined surface, and performing ultrasonic vibration cutting on a material according to a machining track; S3, performing quality detection on the machined material surface obtained by the ultrasonic vibration cutting, completing the machining if the surface passes the detection, and performing step S4 if the surface does not pass the detection; S4, further increasing an amount of rotation of the straight-blade sharp knife during initial rotation around the axis thereof, performing the ultrasonic vibration cutting on the material according to the machining track, and performing step S3.
