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 two simple microprocessor-based gaging systems. One system measures the location an11 diameter of each of three fuel ports inside 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 five seconds. The second system inspects and sorts precision springs. Features measured by the machine include spring rate, free length, and end squareness. The machine accommodates over 80 different springs and maintains a gross throughput of 1,000 pieces per hour.
