Abstract:
1. A method for adjusting the relative position, relative movement, or both, between a workpiece and a tool of a machine tool, the method comprising: generating a first actuating variable for a basic axis in a first controller of a basic axis control system, wherein the basic axis comprises one or more drives acting in a first direction with a first dynamic movement; generating a second actuating variable for an additional axis in a second controller of an additional axis control system, wherein the additional axis comprises at least one drive acting in the first direction with a second dynamic movement that is higher than the first dynamic movement; and generating a third actuating variable, which is fed both to the additional axis control system and to the basic axis control system, in a third controller; wherein a combined movement of the basic axis and the additional axis in the same direction results in an adjustment of the relative position, relative movement, or both, between the workpiece and the tool of the machine tool.
