As rotary ultrasonic machining is just about the sufficient and proficient handling processes for brittle products like ceramics. Consequently, in this study, rotary ultrasonic drilling (RUD) is employed to drill holes on alumina ceramic (Al2O3). This study investigates the result of crucial RUD process variables, particularly vibration frequency, vibration amplitude, spindle speed, and feed price regarding the dimensional precision for the drilled holes. A four-variable three-level
