Claim:
1. A method for providing dynamic state information for at least a part of a coordinate measuring machine that includes a base, a probe head, a machine structure with structural components for linking the probe head to the base, and at least one drive mechanism for providing movability of the probe head relative to the base, wherein the following steps are carried out for execution of the method: defining a dynamic model with a first set of state variables that are related to a set of physical properties of at least the part of the coordinate measuring machine and represent an actual state of at least the part of the coordinate measuring machine; providing the first set of state variables in a database; deriving the actual state of at least the part of the coordinate measuring machine by a calculation based on the dynamic model; monitoring at least one of the state variables of the first set of state variables and, based thereon, determining a change of at least one of the state variables; setting a second set of state variables with updated state variables as to the determined change of the at least one of the state variables; updating the dynamic model using the second set of state variables in place of the first set of state variables; and in response to updating the dynamic model, calculating the actual state of at least the part of the coordinate measuring machine based on at least the second set of state variables.
