ABSTRACT:
An invention is disclosed for positioning an object wherein three point supports provide three contact points which define a first plane. Three additional point supports provide three additional contact points which are not coplanar with the first plane and which define a second plane. The first and second planes are nonperpendicular. The point supports accurately and repeatably position the object for optical measurement of a dimension of the object. The invention can be used in connection with the quality control testing of weldments which attach blade tips to gas turbine engine blades.
