Abstract
Large co-ordinate measuring machines (CMMs) are used for quality assurance in
the automotive and aircraft industry. To monitor and calibrate these machmes, a
new procedure based on the multi-lateration principle has been developed that
uses only the hgh-precision interferometric length measurements of a single
conventional laser tracker to create a "Virtual 2D-Artefact" (set of planar
reference positions). The patent-pending procedure meets high accuracy
requirements and does not require reference objects such as, for example, ball
plates.
1 Introduction
As CMMs are employed for quality assurance, they must to be calibrated and
their performance and accuracy have to be verified at regular intervals. However,
