摘要

超音波在醫療、軍用和工程領域中都被廣泛應用，如腹部超音波、超音波熱療、聲納等。而工程領域中，超音波焊接與切削為常見的加工技術。超音波焊接是利用高頻振盪摩擦生熱，促使加工件產生高熱融化，大幅縮短產品製造時間並可節省成本。超音波切削在加工時可有效降低切削力，使刀具負荷降低，進而提升刀具的壽命。且刀具規律振動，可提升加工工件表面品質，有效提升加工精度。工研院所開發之超音波控制器，自動追頻技術和功率控制技術，可免除因被動元件偏差需調整操作頻率，加上功率補償提高輸出穩定性，可達到良好加工效果。

Ultrasound is widely used in medical, military and industry fields, such as abdominal ultrasound, ultrasonic hyperthermia, sonar, etc.. In the industry field, both ultrasonic welding and cutting are common processing techniques. Ultrasonic welding uses high-frequency vibration to generate frictional heat, which generates high-heat melting the parts, reduces manufacturing time and saves costs. Ultrasonic cutting can effectively reduce the cutting force and the tool load on harder metals, thereby increasing the life of the tool. The regular vibration of the tool can improve the surface quality of the processed workpiece and effectively improve the processing accuracy. This research article is about automatic frequency tracking technology in ultrasonic controller and ultrasonic controller power control technology developed by the Industrial Technology Research Institute, which can eliminate the need to measure the deviation value of passive components and the output of power compensation before the machine to improve stability and achieve good processing results.
