Vibro-Impact Machining - An Application in Surface Grinding

It is well known that vibration plays a major role in human live, though it is mainly seen as negative. However, sciences and engineering have exploited positive aspects of vibration by intelligently applying it to various processes. This paper presents the application of vibration to grinding that accounts for 25% of all manufacturing processes. Here, model of surface grinding is elaborated along with a superimposition of oscillation to the workpiece. Conventional and vibratory grinding are explored and some key findings are reported. The results show that superimposing low vibration to the grinding process leads to a reduction of cutting forces, improved surface quality and results into less energy requirement.
