Abstract

See full text

Embodiments of the invention include a method for compensating a force at a probe element of a probing unit. The probing unit being attached to and moved along a defined moving path with a number of moving points by a coordinate measuring machine for approaching a measuring point at an object. The probing unit comprises an actuator which is arranged and designed in such manner that a force is applicable to the probe element with respect to at least one actuating direction in variable and defined manner, the force depending on an applied actuating signal. Movement information about an expected movement of the probing unit is received, the movement information provides information about an expected displacement behaviour of the probe element relative to the probing unit due to induced forces emerging by moving the probing unit.
