Volumetric Ball Bar Test
Our ball bar test is based on ASME
B89.4.1997 section 5.5.2 and evaluates the volumetric performance of your
CMM. Spheres on the ends of extension bars are measured at 15
different positions throughout the machine's measuring range. The distance
between the two spheres is calculated at each position . Range, ambient
temperature affect, linear error , XY, XZ and YZ squareness and machine
repeatability is reported. The ball bar data along
with a Certificate of Calibration and machine identification tag will be provided.
