HIGH ACCURACY ANGLE INDEXING TABLE

Tsukasa Watanabe, Hiroyuki Fujimoto

Abstract

National Metrology Institute of Japan studied the high precision angle indexing table. We used the principle that NPL reported the indexing accuracy 0.01" in 1984. We verified this principle using the angular primary standard of Japan and proved this principle can exceed 0.001" super-high angular precision.
