Method for producing dental fitting bodies and workpiece for this purpose

A method for producing a dental fitting body with a specified or custom three-dimensionally curved outer contour or for producing a preform of the fitting body with a roughly-shaped outer contour that requires further processing, the method comprising:

• machining a workpiece in a material-removing manner by means of a tool engaging into the workpiece with one or more cutting edges that are arranged on a circumferential surface of the tool,
• rotating the tool about a tool axis, wherein the tool and the workpiece execute a relative movement along a tool path orthogonal or inclined to the tool axis, wherein the tool path has directional components transverse to a run of the contour to be produced,
• wherein the one or more cutting edges have a defined geometry and the tool engages into the workpiece at a cutting are angle alpha of the circumferential surface of less than 90° on average viewed over the entire portion of the tool path at which the machining occurs and the tool engages into the workpiece at an insertion depth of at least twice a tool diameter (D) of the tool, and
• wherein the machining of the workpiece occurs along the tool path following the specified or custom three-dimensionally curved outer contour or the roughly-shaped outer contour.
