Abstract: A method which allows an operator to quickly form a clear picture with regard to the positioning accuracy of a machine part that is displaceable along an axis by means a drive controlled by a controller includes specifying with the controller nominal position values of the machine part in relation to a single axis, wherein the nominal position values are defined by a sine function; displacing the machine part with respect to the single axis in accordance with the nominal position values; determining with a measuring device actual position values of the machine part in relation to the single axis; and visualizing the actual position values of the machine part in relation to the single axis graphically in a circular representation.

Abstract: A device and a method for monitoring collisions between a machine component and a workpiece or another machine component in a machine tool production machine are disclosed. At least one distance sensor is disposed on or in the immediate vicinity of the monitored machine component, whereby the distance sensor generates a distance signal when a tool or another machine component enters the sensor region. The distance signal is transmitted to a machine controller that computes a distance and initiates suitable countermeasures if the distance is outside a permissible range or is otherwise implausible. The device and method are therefore capable of preventatively and reliably detecting a potential collision or the lack of a collision between a machine component and a workpiece or another machine component and initiate appropriate countermeasures.
