Abstract

Stability prediction and chatter avoidance in high-speed machining requires knowledge of the tool point dynamics. In this paper, three advances toward the rapid identification of the tool point frequency response and corresponding stable cutting parameters are described: 1) stable speeds determination using non-contact periodic impulsive excitation of the tool point (produced by spindle rotation and a stationary magnet) in conjunction with once-per-revolution sampling, 2) Receptance Coupling Substructure Analysis for the analytic prediction of the tool point response, and 3) once-per-revolution sampling of the audio signal during cutting to determine stability behavior.
