Abstract
A machine state monitoring system for recurrently determining a change in static or dynamic properties of a geometry of a machine with positional encoders to derive a coordinate information of at least a first machine portion with respect to a second machine portion, which are movable with respect to one another. The monitoring system includes one calibration-monitoring-unit with an optical, at least two-dimensional measuring location sensing unit which is fixed to the first machine portion and configured to optically sense an at least two dimensional location information of an artifact which is provided at the second machine portion, and temporarily moved into a sensing range for determining the change in the static or dynamic properties of the geometry of the machine by a comparison of multiple of such sensings, the compensation parameters are then updated and is used to derive the coordinate information from the encoders.
