Abstract

The invention relates to a machine state monitoring system (2) for recurrently determining a change in static and/or dynamic properties of a geometry of a machine (1). The machine (1) is configured with positional encoders (4) to derive a coordinate information of at least a first machine portion (5) with respect to a second machine portion (3), which are movable with respect to one another by a motorized drive unit (13).According to the invention, the monitoring system (2) comprises at least one calibration-monitoring-unit (6) with an optical, at least two-dimensional measuring location sensing unit which is fixed to the first machine portion (5) and configured to optically sense an at least two dimensional location information of an artifact (3) which is provided at the second machine portion (3), and which artifact is temporarily moved into a sensing range of the calibration-monitoring-unit (6) for determining the change in the static and/or dynamic properties of the geometry of the machine (1) by a comparison of multiple of such sensings, in particular multiple times in the course of a regular operation of the machine.The monitoring system (2) is therein configured to update compensation parameters of a model or map of the geometry of the machine (1) which is used to derive the coordinate information from the encoders (12).
