Direct duplication of free-forms by 5-axis machining consists in the machining of rough clouds of points without surface reconstruction, with the aim at minimizing deviations between the original object and its copy. As discrete 5-axis machining is concerned, the surface is machined area by area with various tool orientations. However, the quality of the machine tool geometry may be source of overlapping errors at area junctions. In the paper, a method for direct duplication by discrete 5-axis machining is proposed. Data segmentation into areas relies on the global visibility of the points, including the visibility of the point cloud by the machine tool. A criterion accounting for the minimization of the overlapping area is also introduced to ensure the quality of the machined object.
