Abstract
A method for ascertaining a correction value for monitoring a fluid bearing of a coordinate measuring machine or other machine tool. Also disclosed is a coordinate measuring machine having at least one fluid bearing. The machine further includes a first element and a second element which are supported against each other by means of at least one fluid bearing. In addition, a control device is provided for controlling the machine. A quantity representing a pressure in the at least one fluid bearing is ascertained as a function of a position and/or orientation of the first element relative to the second element. A correction value for a pressure in the at least one fluid bearing is determined for the position and/or orientation of the first element relative to the second element. The correction value is then stored in the control device, and subsequently used for machining or measuring a workpiece.
