Abstract

The knowledge of the cutting forces and their evolution along time are very interesting for the optimisation and the monitoring of the machining process. The prediction of the time evolution of the cutting forces could allow optimizing tool geometries, or better adapting the cutting conditions and the machine tool to the considered machining operation, in order to minimize the level of cutting forces. It could also be helpful to optimize tool trajectories in CAM software for example. The objective of this study is to improve the qualification procedure of a tool for milling a given material, considering first the local geometry of the cutting edge, and going back then to the global geometry of the considered tool or tool family. This methodology can be adapted for all global shapes of tools, even in the case of complex geometries. Only the local definition of the cutting edge must be constant so that the methodology could be applicated to several tools of the family. This study has also been possible thanks to the use of a dynamometer with accelerometric compensation allowing to obtain good quality signals even at high frequencies of tool rotation.
