Verfahren zum Bearbeiten von Verbundwerkstoffen

摘要

According to invention there is now provided a method of machining and shaping a through opening in a fibre reinforced composite material starting from a preformed hole. At least one rotation symmetrical milling body with substantially smaller diameter than that of the preformed hole is placed in it and the opening is machined and shaped by the milling body partly rotating around its own axis, partly performing a translational movement relatively the edge of the opening. According to the method the fibre reinforced material is hereby oriented in such a way that the axis of rotation of the milling body is essentially perpendicular to the longitudinal direction of the fibres at the edge of the opening. The size and/or form of the finished opening differ significantly from that of the preformed hole. The radial spread of the damages and/or the defects define a lower limit for amount of material removed.
