The approach is compliant with MBN 31007-7 and removes the need for estimates based on incomplete measurements, which can give rise to errors, due to variation in the surface over the circumference of the part, thus affecting process control.
Features of the system include zero contact force (for fragile samples), no tip wear, lower cost of ownership, long working distance, no requirement for detailed knowledge of component dimensions, the potential for large form deviation measurements, less chance of damaging the probe and proven correlation with contact metrology.
