Modélisation et caractérisation des défauts de structure de machine-outil 5-axes pour la mesure in-process

Abstract : This research work deals with the geometric modeling of 5-axis machine tool based on a standardized parameterization of geometric errors with the aim to decrease the volumetric error in the workspace. The identification of the model’s parameters is based on the development of a new standard thermo-invariant material namely Multi-Feature Bar. After its calibration and after a European intercomparison, it provides a direct metrological traceability to the SI meter for dimensional measurement on machine tool in a hostile environment. The identification of three intrinsic parameters of this standard, coupled with a measurement procedure ensures complete and traceable identification of motion errors of linear axes. A model parameter identification procedure is proposed by probing a datum sphere in the workspace and minimizing the time drift of the structural loop and the effects of previously identified motion errors. Finally, the developed model partially identified, allows the characterisation of 95% of the measured volumetric error. Thus, the mean volumetric error not characterized by the model is only equal to 8 µm.
