Résumé

End-milling of free-form surfaces on multi-axis CNC machines are complex and expensive operations involved in the production of many high-value parts, such as molds and stamping dies. To carry out such time-expensive operations, partitioning the surface into zones, in order to mill each zone with the most suitable parameters, is an approach gaining credit in recent years. Data clustering algorithms provide tools that appear to be naturally adapted to perform such a procedure. In this paper, is provided a fine analysis of various clustering algorithms, as well as the feature vectors and the metrics commonly used. Furthermore, the specific problems that may arise when applying clustering algorithms to free-form surfaces partitioning are presented and original solutions to deal with them are proposed.
