Research Abstract

In mechanical devices, parts with complicated concave form are often used. High measurement accuracy is required for the measuring instruments of those parts but the current calibration artifact does not have high accuracy. In this research, a calibration artifact is developed in order to realize high precision measurement of concave form and a calibration method of the measuring instruments is proposed. The proposed artifact is manufactured. Experiments on the calibration method of the measuring instruments are carried out and it is verified that the proposed method is effective.
