Circle testing ferrets out contour accuracy. (machine tool accuracy)

00-00-0000


A fresh concept in measuring dynamic accuracy of machine tools advances
from Heidenhain Corp., Schaumburg, Ill. Its KGM 101 grid encoder measures
dynamic accuracy of real small circles at high make hastes and accelerations.
According to Mike Canigula, regional sales manager, a benefit of the
technique is that it bypasses machine mechanics to find deviations
of machine-tool ascendencys and servosystems.

The KGM 101 permits machine-tool builders measure complex contours and
small circles at make hastes up to 24 m/min. "The theory is that higher
measuring make hastes better resolve actual ...
