Patent ID: 8126586

Claim:
A method for processing workpieces, the method comprising initiating a positioning movement to position a workpiece and a first processing tool relative to each other in a positioning direction; initiating a return-stroke movement to move the workpiece and the first processing tool relative to each other and away from each other in a return-stroke direction transverse to the positioning direction; initiating an outward-stroke movement to move the workpiece and the first processing tool relative to each other and towards each other in an outward-stroke direction transverse to the positioning direction; wherein the return-stroke movement and the outward-stroke movement are executed during the positioning movement; simultaneously obtaining progress values of the return-stroke movement and of the positioning movement; ascertaining a relative return-stroke progress value based on the progress values of the return-stroke movement and of the positioning movement, wherein the relative return-stroke progress value represents progress of the return-stroke movement as a function of progress of the positioning movement; and controlling the outward-stroke movement as a function of the relative return-stroke progress value.
