Apport de la mesure in-situ pour la maîtrise de la qualité des surfaces fabriquées

Abstract : Abstract : Currently, complex parts are produced by more and more automated methods, using 5-axis machine tool or robots. The manufacturing process is based on the definition of a process planning and is divided into different steps from the definition of design requirements. At each step, geometric deviations between the desired shape and the form obtained may appear. Thus the monitoring of manufacturing processes is necessary, requiring 100% of parts checked during the phase of stabilization of the process. So, this work focuses on controlling the quality of the surfaces produced in order to improve the manufacturing process Thus, defining the parameters of the manufacturing strategy is a key element in the manufacturing process. The first part of this work is devoted to improve the prediction of the surface topography generated by the machining process. Another aspect of this work on improvement of the surface quality is focused on the integration of control operations within the machine tool in order to achieve a so-called in-situ measurement. Finally, the last part of the work are aimed to provide digitizing strategies minimizing the number of sensor configurations and the amount of data acquired while controlling quality.
