Abstract: The method for machining a glass pane (1?), wherein the edge (1a) of the glass pane is machined using at least one grinding tool (10), in that the glass pane and the grinding tool, which is set in rotation by means of a motor (11), are moved relative to one another, includes a method step in which a variable that is a function of the power consumption of the motor (11) used to drive the grinding tool is detected along at least a section of the edge (1a?) being machined, and is evaluated to determine the offset of the glass pane (1) with respect to a target position (1).
