Abstract
A process for determining the presence or the dimensions or the correct positioning of a tool which is clamped in the main clamping device of a numerically controlled machine tool opposite which a displaceable component of the machine is arranged, wherein for a displacement of the component towards the workpiece an intended position value is predetermined and the actual position value of the component is continuously determined repetitively, is further developed so that this can be done more simply. This is achieved by selecting the intended position value for the displaceable component so that a stop for the workpiece, which forms part of the displaceable component of the machine would, if a workpiece were not present, be moved to a position which, if a workpiece were present, would lie within the workpiece, and arranging for a signal to be generated if the difference between two successively determined actual position values falls below a predetermined limiting value and the intended position value has not been reached.
