Machine tool system and optical gauging apparatus therein

摘要: In this system an optical gauging apparatus produces two timedisplaced light beams which are directed at opposite acute angles to a nonspecular reflecting surface on the workpiece and focused same point. A lens point receives diffuse reflections from focuses these knife edge intersection of oppositely-inclined surfaces. pair detectors positioned receive respective surfaces operate phase-sensitive amplifier. The amplifier output signal operates servomotor adjust position so as focus its also for causing another cutting tool with respect workpiece.
