Abstract

The ultrasonic vibration reaming (UVR) cutting process is one types of non-Conventional machining process which was tested in this study to show whether its effective method or not. In this process, the tool is imposed on ultrasonic wave to produce vibration along the host cutting movement direction, formed the separation type of vibration process affected by waveform of pulse force. The effect of cutting speed, feed and ream allowance upon the surface roughness and circular degree in reaming a hole of C45 steel were studied in this paper. The results show that the surface quality and machining accuracy of the hole have been improved by using the technology of the present study. At the same time, the cutting force and cutting temperature has reduced correspondingly. In conclusion, it was noticed that the (UVR) is effective cutting techniques for high-precision "thin-hole" machining of the material under this study with respect to the conventional reaming process.
