Abstract
A milling method is disclosed for machining a workpiece of a compressor or turbine wheel in a machine tool. The contour of flow-conducting sections of the compressor or turbine wheel is machined using a rotating milling tool on the workpiece that is accommodated in a workpiece support and is fastened relative thereto for the production process. In order to increase the possibilities to automate the method, the workpiece (8) is placed, by a positioning aid, in a certain position within the workpiece support in a positioning step. The position is used for a subsequent production process and is at least radially predetermined relative to a longitudinal axis. The workpiece is fastened within the machine tool in an axial direction relative to the workpiece support in a clamping step that differs from the positioning step.
