MEASURING AND DISPLAY SYSTEM

摘要

Apparatus for measuring and displaying the amount and degree of movement of a movable element of a machine tool comprising a linear member and a rotatable member angularly disposed thereto and in surface engagement therewith. Either or both of the members is displaceable in correspondence with the movable machine element so as to cause rotation of the rotatable member by interaction of the surface engagement. The rotatable member is provided with means for producing a signal indicative of the incremental rotation thereof. The signal is fed to a display device whereon the degree of displacement from an initial position can be seen.
