Optimisation des conditions de coupe pour l'usinage du bois : application de la méthode Couple Outil Matière au défonçage des panneaux de fibres de densité moyenne

Abstract : Fundamental element for engineers are the features representation of products (machining, production, ...). That permits to guide them during fixing needs of tools and machines in a specifie machining procedure. Cutting conditions determination hardly controls design and manufacturing processes. The machining database it is important in the wood field, specifie to each tool-machine. In this way, each feature could reach particular machining conditions according to his form and composition, for a right surface roughness and safe work. The objective of this research is to analyse the feasibility the predetermining method of cutting conditions, for wood based materials: Couple Tooi Material method. Scope of the application is centred in second processing wood industry products. This method define the working field of cutting tools taking into account the cutting parameters and limiting the number of experiments. The application of this method in Medium Density Fibreboard routing has shown good results. Determination of cutting parameters is possible with checking cutting forces, power and surface roughness. A complete characterisation of studied material was done. To control tool wear, a method was developed, that considers angular variation of cutting forces. Working perspectives are very interesting with the appearance of new material cutting and high speed cutting processes. So, the necessity to compute good working conditions in these wood cutting processes will be easier, with utilisation of Couple Tooi Material data.
