One And Two Dimensional Ultrasonic Vibration Tool

This research is carried out to design and manufacturing of lathe vibration tool and their tests. Firstly، one-dimensional vibration tool is designed and made of the bending vibration mode. One-dimensional vibration tool with half piezoelectric rings is considered to excite the bending mode of tool. Structure of vibration tool is designed in Abaqus software about 20 KHz and then is made with respect to the best obtained geometry of tool for bending vibration mode. Finally، two- dimensional vibration tool is designed and made in Abaqus software for elliptical vibration mode. Also، experiment tests are done in turning operations using one- and two-dimensional vibrating tools with bending and elliptical modes on the copper، respectively and the accuracy of the made instruments is investigated. Results show that vibration tool in turning process reduces the main cutting force.
