Title:
ULTRASONIC CUTTING METHOD EMPLOYING STRAIGHT-BLADE SHARP KNIFE AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/161744
Kind Code:
A1
Abstract:
Disclosed is an ultrasonic cutting method employing a straight-blade sharp knife and an application thereof. The ultrasonic cutting method employing a straight-blade sharp knife comprises the following steps: S1, measuring parameters of the straight-blade sharp knife; S2, the straight-blade sharp knife initially rotating around a knife shaft thereof, thus enabling a rear knife surface of the straight-blade sharp knife to fit to or be away from a processed surface, and performing ultrasonic vibration cutting on a material according to a processing track; S3, performing quality detection on the processed material surface obtained by the ultrasonic vibration cutting, completing processing if the surface passes the detection, and performing step S4 if the surface does not pass the detection; and S4, further increasing the amount of rotation of the straight-blade sharp knife during initial rotation around the knife shaft thereof, performing ultrasonic vibration cutting on the material according to the processing track, and performing step S3. The described method may effectively reduce extrusion on the processed surface by the rear knife surface of the straight-blade sharp knife and improve surface processing quality of the material.
