Stainless steels have a variety of engineering applications and have been machined using many processes. The composite/steel stacks are used increasingly in new generations of aircraft industry, presenting new challenges in drilling holes in these stacks. It has been reported that Rotary Ultrasonic Machining (RUM) could drill composite materials effectively. The feasibility to use RUM to drill stainless steel was also reported. However, there is no report on systematic study on effects of different machining variables in RUM of stainless steel. This paper presents an experimental study on RUM of stainless steels. Cutting force, torque and surface roughness in RUM of stainless steels have been investigated using different machining variables (including spindle speed, feedrate and ultrasonic power).
