Proposition d'une démarche pour identifier les efforts de coupe en présence de talonnage

Abstract : The process damping results from the interference between tool clearance face and the workpiece generated surface and affects the stability of a machining process. Therefore it is necessary to take this phenomenon into consideration during the simulation of machining process. This thesis work presents a practical method for identification, modelling, and numerical simulation of process damping during machining of a workpiece. A special fixture has been used which creates the vibrations conditions necessary to generate the interference between tool clearance face and the specifically designed workpiece. The modelling of process damping is based on the numerical calculation of the interference volume between tool clearance face and the workpiece generated surface. The tool and workpiece geometries are represented by z-buffers whose relative positions at each instant permit to evaluate numerically the interference volume. The process damping coefficients are then estimated by minimization of the error between measured cutting force and the simulated cutting forces.
