Notes:
AIST (National Institute of Advanced Industrial Science and Technology) has proposed anew calibration method of gear measuring instrument using a ball artifact consisting of two masterballs and an optical flat base (DBA). We measure a circular arc instead of involute tooth form.Difference of the distance between the arc of the master ball and involute curve can be calculatedtheoretically. For the calculation, center distance between two balls is required and the value ofmeasurement uncertainty is less than 0.1 'm and also should be traceable to national standard oflength. This paper reports on a new method and an originally developed instrument to measure thecenter distance between two balls using laser interferometer. The expanded uncertainty inmeasurement of a center distance of 44 mm was 21 nm
