Abstract

Multi-axis milling is a technique that enables numerous machining applications, and in particular the finishing of complex surfaces (machining of moulds, matrices and prototypes). The high operational cost of multi-axis milling drives the suppliers of CAM software to develop simulation machining programs. Today, simulation machine tools integrate the ideas of trajectory and collision, but do not take into account the calculation of cutting speeds and cutting forces, or the calculation of stresses.

This paper is about the calculation of instantaneous sections in multi-axis milling, in order to model the cutting forces. All the models used to date have been formed on the principle of two circles set over from the feed movement by tooth for the calculation of the instantaneous section. For this study, the real travel of the tooth, which is a cycloid, will be taken into account.
