Abstract
Official abstract text for this publication.
A measurement system has a surface sensing device mounted on an articulating probe head, which in turn is mounted on a coordinate positioning apparatus. The surface sensing device is moved relative to a surface by driving at least one of the coordinate positioning apparatus and probe head in at least one axis to scan the surface. The surface sensing device measures its distance from the surface and the probe head is driven to rotate the surface sensing device about at least one axis in order to control the relative position of the surface sensing device from the surface to within a predetermined range in real time.
First claim
Opening claim text (preview).
The invention claimed is: 1. An articulating probe head comprising; a first member; a second member that is mounted for rotation with respect to the first member about a first axis: a third member that is mounted for rotation with respect to the second member about a second axis, and on which a surface sensing device is mountable, the second and third members providing rotational movement of the surface sensing device about the first and second axes; and a first rotary measu…
