초음파 절삭가공에 의한 절단면의 Burr 높이의 최적화 실험

초록

Ultrasonic cutting technology that can perform micro-cutting is applied for convenience of work to cut out unnecessary parts of a clear aligner during the manufacturing process of transparent devices for orthodontics. Ultrasonic processing is not limited physically or chemically by the material of the workpiece because it is a non-thermal, non-chemical, and non-conductive method. Owing to these characteristics, it is suitable for processing brittle materials such as glass and ceramic regardless of electrical conductivity. An ultrasonic cutting system is produced by applying this ultrasonic cutting technology, and the heights of burrs on the cut surface of PET sheets are included in the experiment. The burr height is measured by setting the cutting speed to 100, 300, 500, 700, and 900 mm/min, and the power to 50, 60, 70, 80, 90, and 100 %. Then the optimal conditions are derived.
