Patent ID: 8538574

Claim:
A method for generating control data for controlling a predetermined tool on a machine tool for machining a clamped workpiece from a blank to a finished part, comprising: the step of generating path data by a hardware processor that indicates which machining path a predetermined tool is to travel at a feed rate and with a tool orientation relative to the workpiece, wherein generating machining geometry model data of a machining geometry of the workpiece, which describes the removal state of the workpiece at a particular machining time, providing finished part geometry model data which describes a finished part geometry of the workpiece, generating difference geometry model data which describes a difference geometry of material which has yet to be removed in order to achieve the finished part geometry, and generating path data on the basis of the difference geometry model data if the predetermined tool removes a maximally large part of the volume of the difference geometry of the workpiece per time unit while traveling the machining path in dependence of a maximum machining volume for the predetermined tool, wherein repeating one time or multiple times the steps of generating machining geometry model data, generating difference geometry model data, and generating path data on the basis of the difference geometry model data in this sequence, wherein at least second machining geometry model data of a second machining geometry of the workpiece and second difference geometry model data are generated at a particular second machining time upon a first repetition of the steps after a tool predetermined for a first machining path has traveled the first machining path on the basis of first path data, and second path data are generated on the basis of the second difference geometry model data if a tool predetermined for a second machining path removes a maximally large part of the volume of the second difference geometry of the workpiece per time unit while traveling the second machining path in dependence of a maximum machining volume.
