摘要

In this paper we present the second generation Receptance Coupling Substructure Analysis (RCSA) method,rnwhich is used to predict the tool point dynamic response for milling applications. This method divides the spindleholder-rntool assembly into three substructures: the spindle-holder base; the extended holder; and the tool. The toolrnand extended holder receptances are determined analytically, while the spindle-holder base subassemblyrnreceptances are determined experimentally using a 'standard' test holder and finite difference calculations. Tornpredict the tool point dynamics, RCSA is used to rigidly couple the three substructures. Experimental validation isrnprovided.
