The simulation of the global Part-Tool-Machine-System (PTMS) dynamic behaviour during cutting is one of the validation procedures used to prepare a machining process. Various objectives could be reached when using simulation and this depends on the user who could be the machine-tool designer, the tool designer or the machinist. Two kinds of mathematical models, in order to develop simulation programs, are suggested for the (PTMS) modelling: the first one describes the (PTMS) as a mechanical structure and the second one describes the interaction between a tool and a worked part. In our study, we are interested in the second mathematical model and we must firstly establish a dynamic cutting force law, including different parameters and a damping term. The aim of this research paper is to suggest an identification method for the dynamic cutting force law parameters, calling (CDFC), by using a dynamometer in the case of an orthogonal cutting process. |
