METHOD FOR PRODUCING DENTAL FITTING BODIES AND WORKPIECE FOR THIS PURPOSE

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.degree. 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.
