Abstract
In the method for producing medical, in particular dental fitting bodies with a specified or custom three-dimensionally curved outer contour or preform of the fitting body with a rough outer contour, which has an allowance relative to the outer contour, a workpiece from which the fitting body or its preform is produced, is machined in a material-removing manner by means of a tool engaging in the workpiece The tool path has directional components transverse to the run of the contour to be produced and the cutting edges have a defined geometry. The tool engages into the workpiece at a cutting arc angle alpha of the circumferential surface of less than 90° on average and at an insertion depth of at least twice the tool diameter (D) and the machining of the workpiece occurs along a tool path with directional components contrary to a machining direction following the outer contour.
