Abstract
Devices and related methods of controlling relative movement between a tool of a machine tool and a work piece including dividing a total desired relative tool to workpiece movement in a direction of an axis into a first movement component and a second movement component; controlling the first movement component with a first closed-loop axis control; determining a resulting movement quantity corresponding to the first movement component; feeding a position error from the first closed-loop axis control to the second closed-loop axis control controlling the second movement component in a closed-loop with the second closed-loop axis control, including adjusting for the position error of the first movement component.
