Abstract:
This work presents an approach to perform interlaboratory comparison of Articulated Arm Coordinate Measuring Machines (AACMM) with Virtual Spheres Plate (VSP) gauge. This gauge has a determined number of pyramidal inserts having four conic holes each. These inserts were designed to fit virtual spheres with coordinates of the four points determined by measurement. The gauge has to be delivered to the laboratories under evaluation and the diameter and the center-to-center distances among the virtual spheres must be determined to apply normalized error analysis. The results proved suitable to evaluate the machine errors and to compare these machines.
