Mass finishing is a centuries old technology, with barrel tumbling dating back to the ancient Romans. For many years, rotary tumbling remained the primary mass finishing technique. In 1957 however, a major advance in mass finishing technology occurred as vibratory tubs were introduced with round bowls following shortly thereafter in the early 1960's (Kittredge 1989). Vibratory finishing utilizes the energy derived from vibration to finish parts through a complex surface abrasion process. Vibratory finishing is widely used, but not well understood, and there is a need for research into the process parameters as well as the development of methods of process design and optimization. This research presents a fundamental analysis of the material removal in vibratory finishing which previously has, been lacking. A mass removal model is proposed and compared against experimental data from vibratory finishing. The thesis consists of eight chapters and includes five appendices...
