Abstract

The measurement volume A of a given coordinate-measuring machine is increased by a device which consists (i) of a support plate (15) which can be displaced on the surface of the machine table (1) into at least two defined positions and (ii) of a device (16a-c, 17a-c) for measuring the position of the support plate in these different positions. The workpiece to be measured is clamped on said support plate (15) and can then be measured, section by section.
