The surface quality of the parts is one of the major objectives of the use of the high-speed milling (HSM). Tool path interpolations affect the machining operation of complex parts in HSM. In this paper, the influence of the different types of interpolation of the computer-aided manufacturing (CAM) on the surface roughness in the HSM machining of free forms is studied. To do this, a simulation tool of the surface texture for each type of interpolation is proposed. Then, experimental measurements expressing surfaces condition are carried out. To validate our approach, theoretical results with experimental ones are compared. As results, CAM interpolations of tool paths have demonstrated an important impact on the surface texture. In fact, a simulation prediction tool has confirmed the advantages of using polynomial interpolations in order to ameliorate the quality of the machined surface.
