Ultrasonic Vibration Turning of Stainless Slender Shaft: Investigation on Run-Out of Two Clamping Methods

Article Preview

Abstract:

Slender shaft is of high slenderness ratio and bad rigidity. The factors, for example, cutting force, cutting heat, vibration and so on, which are produced in the processing, will affect directly the size precision of workpieces. In this research, slender shaft is 304 stainless steel bar, with length of 450mm and diameter of 10mm. In order to resolve the problem of slender shaft machining with CNC slant bed lathe not configured with the follow-rest, a self-made follow-rest was developed. With both ends clamped processing mode, it is possible to use the CNC lathe turning slender shaft. Moreover, better effect of turning of slender shaft can be attained if ultrasonic vibration cutting technology is involved. After turning process is completed, size accuracy is checked to evaluate the effect of self-made follow-rest and both ends clamped processing mode. In this study, the experimental results show that quality of the slender shaft processing has been significantly improved with the use of self-made follow-rest and both ends clamped processing mode, which has definite effects on solving the practical problems of processing.
