A control device for controlling a machine tool, wherein the machine tool and the control device are configured such that a tool and/or workpiece disposed on the machine tool can be moved with at least one first speed and at least one second speed. When switching from a movement with the first speed to a movement with the second speed, the tool or the workpiece is at first stopped prior to the execution of the movement with the second speed, if the second speed is greater than the first speed by at least a predetermined factor. The control device has an input device for triggering the movement with the second speed, and the subsequent execution of the movement with the second speed is triggered by an operator input on the input device.

The present invention relates to a computer program for producing a graphical user interface (100) of a manipulator program and to a method for navigation through a manipulator program, wherein the manipulator system (1) controlled by the manipulator program comprises at least one manipulator (30). The manipulator program comprises at least one set-down point (AP1 to AP5). The user interface (100) has a graphical program progress indicator (150) which indicates the current program progress of the manipulator program and the at least one set-down point (AP1 to AP5) of the manipulator program. The at least one set-down point (AP1 to AP5) indicated can be selected by a user, and the manipulator program is set up to control the manipulator system (1) in such a manner that the system assumes a system state assigned to the selected set-down point (AP1 to AP5) in response to the selection. The method comprises the steps of: providing a manipulator program; producing the graphical user interface; stopping the manipulator program; receiving a selection of a set-down point on the program progress indicator of the graphical user interface; and guiding the manipulator program to the selected set-down point, with the result that the manipulator program controls the manipulator system in such a manner that the system assumes the system state assigned to the selected set-down point. Such navigation may be advantageous, in particular, in the field of debugging, error correction and parameter correction or parameter optimization.
