Abstract

The invention relates to a method for producing dentures by milling a workpiece. The inventive method is characterized in that in the event of a change in the load on the workpiece or on the milling tool, or on the workpiece and on the milling tool, determined before the milling begins and occurring during the milling, the relative speed between the milling tool and the workplace is varied without using a regulation technique.
