Method for determining thermally induced change in spatial position of machine tool section, involves comparing values of two spatial positions of machine tool sections, and determining thermally induced change in positions from comparison

The method involves detecting two values of two spatial positions of machine tool sections based on measurements of two measuring devices, where machine tool sections are movable along a machine tool axis. The values of the two spatial positions of machine tool sections are compared, and thermally i...

Zusammenfassung:	The method involves detecting two values of two spatial positions of machine tool sections based on measurements of two measuring devices, where machine tool sections are movable along a machine tool axis. The values of the two spatial positions of machine tool sections are compared, and thermally induced change in the spatial positions is determined from the comparison result. A position of the machine tool sections is determined by a measuring rod with detection of the spatial position value of the machine tool sections by one of the measuring devices. Independent claims are also included for the following: (1) a computer program product for determining or correcting a thermally induced change in a spatial position of a machine tool sections of a machine tool on a machine tool axis (2) a machine tool for machining a workpiece.
