Tool path definitions and their interpolation for optimized 5-axis High-Speed Machining

Abstract : More than ever, productivity is a key factor for industrial applications and manufacturing processes to keep competitivity. The manufacturing process consists in various activities linked together to obtain the final product: CAD model definition, CAM computation and production. Within this context, 5 axis high speed machining is composed of the following key activities : tool-path generation on the CAD model, interpolation of theses geometries by the CNC, actual follow-up by the machine tool during the execution and high speed cutting. Nowadays, to optimize the final part, the study of each task cannot be performed separately without considering effects and links inside the whole process. The talk will deal more precisely with the activities of tool path generation and CNC interpolation considering their influences on the actual machine tool behavior. It will highlight recent research developments to simulate the process (macro geometry and surface topography of the machined part) and ways to optimize the geometry definition and its discretization considering geometrical and kinematical effects to manage quality and productivity.
