MACHINE VISION SYSTEMS ARE OFTEN USED IN GAGING APPLICATIONS. IN SOME CASES THE INSTALLATION AND RESULTS CAN BE VERY SUCCESSFUL BUT IN OTHER CASES THE RESULTS CAN BE VERY DISAPPOINTING. THIS PAPER DISCUSSES THE INFLUENCE OF SOME COMPONENTS OF A VISION SYSTEM ON GAGING ACCURACY AND PROVIDES A METHOD FOR EVALUATING MACHINE VISION SYSTEMS FOR GAGING APPLICATIONS. FOLLOWING THIS METHODOLOGY, A TEST ENGINEER CAN AVOID USING THE VISION SYSTEM IN A WRONG TYPE OF GAGING APPLICATION. CALIBRATION, PARALLAX, AND CHAMFERED EDGES ARE BRIEFLY DISCUSSED AT THE END OF THE PAPER.
