Unformatted text preview: tting edge profile. Once this operation performed, the intersection between this envelope and each z-axis is computed and associated coordinates hi are stored. These two steps then are repeated for each trajectory of the milling strategy employed. The resulting machined surface is finally represented by the minimum value of h found for each zaxis considering the whole displacements of the tool. This method is implemented by Baek [Baek et al., 2001] to predict the surface roughness. A complete analytical description and resolution of the problem is used for that purpose. He starts by performing a complete analysis of the different profiles left in the part, by the cutting edges, during one revolution of the milling tool. Each profile is represented by an equation. The profiles are then compared and only the portions that lead to the maximum machined depth are kept. The final result is expressed in the form of a function defined by intervals. Anyway, this study is seriously limited because only the machining profile of the middle cutting plane...
