Abstract

Receptance coupling substructure analysis (RCSA) allows to estimate tool-tip FRF of different spindle-holder-tool configurations with the minimum set of measurements. This technique requires accurate holder-tool connection modelling. In this paper fully predictive modelling strategies of holder-tool connection are presented. Proposed procedures are implemented in FE environment, without the use of any tuning experimental test, using solid elements to model the most common connection types. The main advantage of proposed approaches is to model the entire toolkit without requiring lumped stiffness and iterative procedures. Resulted toolkit FE model can be used in RCSA providing accurate tool-tip FRF for chatter prediction.
