Abstract

The invention relates to a method for guiding the movement of a movable machine element (8) of a numerically controlled tool machine or production machine on a predetermined movement path (s) of the machine element (8). Supporting points (32) are defined in the working area (31) of the machine. The maximum possible path jerk () and/or the maximum possible path acceleration ({umlaut over (s)}) and/or the maximum possible path speed ({dot over (s)}) of the machine element (8) is determined or predetermined at on each supporting point (32) and the movement of the machine element (8) on the displacement path (S) is carried out using the maximum possible path jerk () and/or the maximum possible path acceleration ({umlaut over (s)}) and/or the maximum possible path speed ({dot over (s)}) of the machine element (8). Said method can be produced in a simple and economical manner with optimum guiding of the movement of a movable machine element (8) of a numerically controlled tool machine or production machine on a predetermined movement path (S) of a machine element (8).
