Abstract: The invention concerns a milling tool (10) with reduced noise emission for machining panel-like pieces of wood. The reduction in noise emission is brought about by reducing the vibrations produced in the tool and workpiece and by proportioning the cut, machining being carried out in two stages. The greatest part of the chip volume (first stage) is removed under favorable noise-emission conditions using a special cutting geometry. The tool and workpiece vibrations are reduced by a clearly reduced rise in the shear force pulse using a special cutting tooth geometry. The chip volume removed under these conditions is only small (second stage), and so good quality machining can be attained.
