Abstract
A method of machining a workpiece using a rotary milling cutter is disclosed. The method includes rotating a tool head with a shaft, rough cutting a workpiece with a rough cutting edge of a first partial body to remove a first amount of material from the workpiece, and finish cutting a rough-cut surface of the workpiece with a finishing edge of a second partial body to remove a second amount of material from the workpiece, the second amount of material being smaller than the first amount of material. Both the rough cutting edge of the first partial body and the finishing edge of the second partial body simultaneously engage the workpiece to perform both rough cutting and said finish cutting of the workpiece in a single cutting operation.
