PRECISION MACHINING OF MASS-PRODUCED COMPONENTS SUCH AS AUTOMOBILE ENGINES AND TRANSMISSIONS REQUIRES APPROPRIATE GAGING TO CONTROL THE MANUFACTURING PROCESS. TWENTY-FIVE YEARS AGO, THE GAGING TECHNOLOGY USED WAS BASED ON MONITORING THE FLOW THROUGH AIR JETS. ADVANCES IN ELECTRONICS BROUGHT ABOUT THE APPLICATION OF ELECTRONIC GAGES USING EITHER TRIGGER PROBING, AS FOUND ON COORDINATE MEASURING MACHINES, OR LINEAR VARIABLE DIFFERENTIAL TRANSFORMERS MORE COMMON ON DEDICATED GAGES. WITH THE INTRODUCTION OF ELECTRONIC GAGING CAME A GREATER DEPENDENCE ON ELECTRONIC SIGNAL CONDITIONING AND DATA COLLECTION AND DISPLAY. THIS HAS EVOLVED TO THE POINT WHERE COMPUTERS ARE THE BASE CONTROLLER FOR COMPLEX GAGING SYSTEMS. OPTICAL GAGING ALSO HAS EVOLVED. OPTICAL COMPARATORS, WHICH PROVIDE TWO-DIMENSIONAL VIEWS, ARE EXTENSIVELY USED IN THE QUALITY CONTROL LABORATORY. MORE RECENTLY, OPTICAL GAGING EXPA
