Abstract: A tool for machining composite material parts and a machining machine including such a tool. The tool has a substantially cylindrical main body. The main body includes a polishing part with a diameter D1, with a main axis and an abrasive part with a diameter D2, with D2 <D1, such abrasive part being centered on the main axis. The abrasive part includes, at its end at least one cutting element intended to enable penetrations of the tool into the composite material parts.

Abstract: A milling tool has a cutting edge geometry with a main cutting edge, a cutting corner, optionally with a bordering planar cutting edge segment, and a secondary cutting edge. The tool is used for milling to achieve the smoothest level surface possible parallel to the rotational axis of the milling tool. Each main cutting edge is formed to result in a generatrix of the envelope curve described by the rotation of the milling tool that has a first outwardly curving segment and a second inwardly curving segment. The first segment increases in its distance from the rotational axis from the beginning of the segment to the end of the segment. The distance of the second segment decreases from its beginning towards its end. The tangents at each point of the second segment encompass an angle ?2 of more than 0° and up to 3° with a parallel to the rotational axis.
