Paper Abstract

This paper addresses dynamics and control issues encountered in development of a smart spindle unit (SSU) for suppressing chatter in milling operations. The SSU comprises a suite of strain, displacement and force sensors coupled to four, high-force, electrostrictive ceramic actuators through a digital control processor. The operating principles of the SSU are discussed, and salient dynamics of the SSU and generic milling tools are explored in this context. Dynamic characteristics measured using the SSU sensors are presented and discussed relative to their influence on chatter and control of chatter.
