Abstract

Tooth profile measurements were calibrated using a double ball artifact that is traceable to a national standard of length. From the calibrated results, an evaluation technology that quantifies the uncertainty of tooth profile measurement in a 1-to-1 correspondence with a tooth profile of arbitrary specifications was established. In this evaluation technology, the work of calibrating the measuring machine has been minimized, and measurement simulations have been made feasible by modeling the statistical properties, as well as algebraic calculation from the model during tooth profile measurement, enabling the reliability of tooth profile measurement to be statistically evaluated. As a result, during tooth profile inspections on the manufacturing floor, practical inspection accuracy is now guaranteed.
