Paper Abstract

The application of electro-optics to industrial metrology is discussed. Principles of operation and methods of implementation are illustrated by a detailed examination of three electro optical microprocessor based gaging systems. One system inspects and sorts precision springs. Features measured by the machine include spring rate, free length, and end sqthiireness. The machine accommodates over 80 different part number springs and main-tains a gross throughput of 1,000 pieces per hour. Also described, is a small parts measuring machine used to measure features such as diameter, taper, roundness, sphericity, concentricity, length, thread quality, etc. on parts such as ball studs and bearings used in automobile steering systems. The third machine measures the location and diameters of each of three fuel ports in-side the bore of a diesel fuel injector barrel. The machine can handle any one of four different part numbers with an inspection cycle time of six seconds. A description of the mechanics, optics, software, calibration, and operation on each of the machines is given.
