Abstract
A rotating displacement sensor located on the tool holder under the cutting tip works equally well in many directions so it can perform in-process and tool condition compensation of contoured parts. The air nozzle is rotated by a turret-mounted motor and has a rectangular displacement sensing orifice whose plane is kept parallel to machined surfaces. An automatic control continuously adjusts the nozzle rotation to minimize the air gage output voltage and measured distance from the nozzle to the workpiece. The device may be used strictly as an inspection head.
