Abstract

As interest in high-speed machining techniques grows among world manufacturers, efficient methods for obtaining the tool point frequency response (used as input to analytic or numerical chatter prediction/avoidance models) become more important. We describe the application of receptance coupling substructure analysis to the analytic prediction of the tool point dynamic response using frequency response measurements of individual components coupled through appropriate connections. This paper demonstrates experimental verification of the receptance coupling method for various tool geometries (e.g., diameter and length) and holders (HSK 63A collet and shrink fit). System changes (and the corresponding critical stability limit deviations) are predicted for tool length variation in a tool tuning example. Mode shape prediction is also shown.
