Tool point frequency response prediction for high-speed machining by RCSA

The implementation of high-speed machining for the manufacture of discrete parts requires accurate knowledge of the system dynamics. We describe the a pplication of receptance coupling substructure analysis (RCSA) to the analy tic prediction of the tool point dynamic response by combining frequency re sponse measurements of individual components through appropriate connection s. Experimental verification of the receptance coupling method for various tool geometries (e.g., diameter and length) and holders (HSK 63A collet and shrink fit) is given. Several experimental results are, presented to demon strate the practical applicability of the proposed method for chatter stabi lity prediction in milling.
