Abstract

In a control method for the movement of a tool with a machine tool, the machine tool involves a numerically controlled machine tool, in order to produce an arbitrary required surface of a workpiece by machining. A numeric path program is created which describes the machining of the workpiece with the tool at machining points and which controls the control device. The numeric path program produces a path with respect to the geometric nature of the surface of the workpiece to be machined, with the path including a plurality of sample points and individual paths, with each individual path connecting a pair of the sample points to each other. The numeric path program is evaluated and selected on the basis of a geometric quality criterion, with the geometric quality criterion having continuity as at least one criterion.
