| Summary: | 碩士 === 國立虎尾科技大學 === 機械與機電工程研究所 === 95 === In this study, a supersonic mechanism was adapted as a vibration source. Supersonic vibration was mounted on a traditional milling machine for carbon steel (S45C) milling. Produced high-frequency and small periodic amplitude characteristic, can be used in traditional cutting. The wave shape can be changed closely to a pulse wave from a sine wave in the relation between cutting rate and time. Cutting force can be reduced; the stability and machining accuracy can be improved in ultrasonic aided vibration system. Taguchi method was used to analyze the process parameter such as cutting force, surface roughness and flak wear. Factor such as mill depth (mm), milling speed (rpm), feed rate (mm/min), and vibration frequency (KHz) were checked in the experiments for an optimization process in vibration milling.
