This study applied ultrasonic cutting technology to solve the problem of lowering the cutting efficiency in the manufacturing process of transparent orthodontic braces, and in particular, used conical blades to improve cutting quality and efficiency. The existing process relied on manual work, resulting in problems such as quality deviation, labor strength, and shortening the tool life. Laser cutting technology was also attempted, but there was a limitation due to the generation of heat-affected parts and the generation of harmful by-products. Accordingly, in this study, a no-pressure cutting method using ultrasonic vibration (20~40 kHz) was introduced, and optimal process conditions were established based on the experimental planning method. Ultrasonic cutting using a conical blade minimized heat generation and improved the quality of the cutting surface, and secured stability in continuous processing. As a result of the experiment, the cutting efficiency and surface quality were superior to those of existing scissors cutting and CO₂ laser cutting, and the applicability of the automation process was confirmed. This study is a core technology that can realize the automation and high efficiency of manufacturing transparent correctors, and is expected to be expanded to the dental industry and precision processing industry in the future.
