Claim:
1. A method for compensating a force at a probe element of a probing unit, the probing unit being attached to a coordinate measuring machine and moved along a defined moving path with a number of moving points by the coordinate measuring machine for approaching a measuring point at an object, wherein the probing unit comprises an actuator which is arranged and designed in such manner that a counterforce is applicable to the probe element with respect to at least one actuating direction in variable and defined manner, the counterforce depending on an applied actuating signal, wherein the method comprises: receiving movement information about an expected and/or measured movement of the probing unit, the movement information provides information about a force affecting the probe element due to movement of the probing unit, deriving a force parameter for at least one particular moving point based on the movement information, determining the actuating signal for the at least one particular moving point based on the derived force parameter, the actuating signal provides applying a defined counterforce to the probe element by the actuator regarding the force affecting the probe element at the particular moving point.
