Vibration cutting (VC), elliptical vibration cutting (EVC) and ordinary cutting (OC) of In738 work-pieces have been experimentally investigated in the present research. The experiments were carried out by using single crystal diamond tool and ultra-precision CNC lathe. Vibration frequency is 36.16KHz and the amplitude is . The influence of various cutting parameters including cutting speed, feed-rate, vibration amplitude and phase angle on the cutting force, surface roughness and tool life have been studied and the results have been compared. The results indicate that the cutting force in EVC is much less than the two other processes. The surface roughness in both the cutting and feed directions was also less than those in other processes.
