Abstract :
[en] This article presents a new stability prediction tool. The method is based on the dynamic behaviour of both milling tool and workpiece, computed using finite element method. Dynamic behaviour is expressed under the form of transfer functions and used to predict stability lobes at each tool position. The unconditionally stable depth of cut is then stored and displayed on a graphic representation of the machined surface under the form of colour axis, named stability map. An application of the method on a Renault cylinder block is presented as an illustration. (C) 2006 Elsevier Ltd. All rights reserved.
