| Summary: | 碩士 === 國立臺灣海洋大學 === 機械與機電工程學系 === 99 === According to the accuracy of the original machine, the processing of a future piece, the continuous improvement of not more than continuous improvement in the degree of processing machinery, precision components to be accurate, it would take many times after finishing in order to produce high-precision parts.
Therefore, this study uses the flexible handle weakening and paste the piezoelectric ceramic on the knife handle, resulting in ultrasonic elliptical vibration cutting , and though the trip institutions (Quick Stop Devices: QSDs) to observe the cutting chips to prove the feasibility of turning.
The results showed that ultrasonic elliptical vibration cutting on surface roughness in the cutting speed of 10m/min,0.04mm amplitude 1.2um depth of cut feed rate from 0.10 to 0.13 in the flexible vibration between the rigid and flexible cutting is better than cutting, and it’s the maximum rate of improvement 68% improvement on the rigid, flexible cutting for 62% improvement, and with the amplitude of the increase is to improve the rate of increase.
