In a method of machining a blank from all directions using at least one machine tool, such as a milling machine, production of the ready-to-use, measured component which is controlled and classified with regard to quality, such as a turbine blade, occurs in as few steps and setups as possible with the use of machine tools and milling machines that as far as possible are of identical design. The blank, in a first machining step, is held by at least one first adapter and a first region is given its final partial shape corresponding to the intended use by a machine tool or milling machine. In a second machining step, the partly machined blank is held by at least one second adapter in the first, finally machined region, and the remaining region is given its final overall shape corresponding to the intended use by a machine tool or milling machine.
