This paper presents an investigation of the effect of process parameters on micro rotary ultrasonic machining (micro RUM) performance. Influence of main machining parameters such as spindle speed, abrasive grit size, vibration amplitude on the material removal rate (MRR) was studied. Experiments were conducted to study the effect of different coolants, static load and tool tip geometry. Experiments were also conducted using a constant feedrate mode to monitor the cutting forces developed during machining at different spindle speeds. Preliminary experiments indicated that MRR increases in the presence of ultrasonic vibrations, coolant and tool rotation. Published in the Transactions of NAMRI/SME, Vol. 38, 2010, pp. 113-120.
