  • Abstract

    The main objective of this study is to investigate the influence of spindle speed on the surface roughness (Ra) of dental zirconia during Rotary Ultrasonic Machining (RUM) and traditional milling. The spindle speed set at range 2000- 6000rpm, with constant feed rate, frequency, and depth of cut for both RUM and traditional milling. The results show that when the spindle speed at 6000rpm, frequency at 23 kHz, feed rate at 50mm/min and cutting depth of 0.025mm created the best outcome of Ra with value of 0.182 μm. The maximum differences in Ra value between RUM and traditional milling is 42% at spindle speed of 6000 rpm.
