Ultrasonic Elliptical Vibration Turning Studty for Precision and Ultra-Precision Workpiece

Abstract:

Based on ultrasonic elliptical vibration cutting (UEVC) model, kinematical formulas of elliptical vibration cutting(EVC) is established, the paper presented relationship of vibration parameters effecting on surface roughness, machining accuracy and machining efficiency, revealed UEVC characteristics of high frequency and small amplitude are more conducive to improve surface roughness, advance EVC machining efficiency. Experiences of cutting the weak rigidity workpiece by the designed adjusting frequency elliptical transducer is proved that compared conventional turning, increasing vibration frequency and decreasing amplitude are result in improve surface roughness, and compared low frequency EVC, decrease amplitude are result in reduce the height of vibration ripples in cutting direction, and advance machining efficiency. So high frequency and small amplitude EVC is more conducive to precision machining and ultra-precision machining.
