Department of Industrial and Management Systems Engineering: Dissertations, Theses, and Student Research

The demand for miniaturized device and components is rapidly increasing in fields of aerospace, energy, optics, electronics and communication, automation and medical. Rotary Ultrasonic Machining (RUM) is capable of machining hard and brittle materials such as advanced ceramics, glass and silicon used in many industries. Rotary Ultrasonic Machining (RUM) is a hybrid machining process in which material is removed by conventional grinding and ultrasonic machining. Micro RUM is a downscaled version of a macro RUM and is similar to micro Ultrasonic Machining (micro USM), where the vibration takes place in work piece instead of tool.
