Development of a cutting forces model applicable to a family of tools: case of milling of hard steels

Abstract : This research work deals with the study and the modelisation of cutting forces in milling of hard materials. The knowledge of cutting forces, and their time evolution, are useful data for optimisation and monitoring of the manufacturing process. The prediction of the cutting forces time evolution could allow to optimise the tool design, or to better adapt the cutting conditions and the machine tool to the considered machining operation; in order to minimise the force level or to stabilise it, and then to avoid the force "peeks" with high amplitudes that are dangerous for the tool life and for the capacities of the machine. The knowledge of cutting forces could also help optimisation of tools trajectories in a CAM software for example. The objective of this study is to improve the procedure of qualification of a tool machining a given material, considering as first step the local geometry of the cutting edge, and going back then to the global geometry of the tool or of the considered tool family. This method has the advantage of being adapted to any global shape of tool, even in the case of milling cutters with complex geometries. Only the cutting edge definition must be conserved to apply the procedure to several tools of the same family. Finally, this study has been possible in high speed conditions thanks to a dynamometric sensor with inertial compensation allowing to obtaining good quality signals even at high frequencies.
