Abstract	High-speed milling permits to machine materials with increased productivity. For a reliable application of this strategy, it is crucial to avoid tool chipping during the machining; in practice, this implies underestimating tool life. The formation of chipping induces vibrations, high temperature on tool nose, and poor surface quality. This is a problem when it represents the last operation. A better comprehension of how a damaged insert works is useful to design a reliable monitoring system. More researches use several sensors to monitor the health state of the milling tool, like force signal, current signal, acceleration, acoustic emission, etc., and complex elaboration systems have been considered. The objective of this paper is the proposal of a model to analyze the chipping of multi-tooth milling tool. First milling tests are carried out on a milling center and cutting forces are measured. The experimental data were elaborated and a suitable model is set up. The finite element method (FEM) is considered and simulations were performed using SFTC Deform 2DTM, a Lagrangian implicit solutor. The material model and the friction law are calibrated following an appropriate procedure. In this work, face milling using multi-tooth milling tool is considered. Face milling are very common operations in several industrial sectors. The results show the FEM model is able to simulate the standard deviation of feed force during the chipping. A regression model between chipping scar dimension and feed cutting force is presented in order to summarize the obtained results.
