| Summary: | This programme of research is concerned with investigating novel methods for enhancing the machining of metals in terms of increasing material removal rates while maintaining surface finish and dimensional tolerance. This thesis provides a detailed investigation of the interaction between the drive control system, the power converter and the cutting process. Specifically, the research explores the merits of high speed and precise torque modulation of the drive and its influence on the cutting tool to suppress chatter in milling operations. The coupling between the controller and power converter behaviour and the dynamic cutting conditions is the key novelty in this research. |
