  • Method and apparatus for obtaining and analyzing an image of a elongate slot
    Patent number: 5517310
    Abstract: An inspection device and method determines the accuracy of an irregular shaped elongate slot disposed through a piece part supported on an indexable turntable. The inspection device includes a movable illumination device for directing backlighting towards the piece part and illuminating the elongate slot, and a camera for taking a picture of the illuminated irregular shaped elongate slot and delivering an image of the irregular elongate slot. A vision system determines actual key characteristics (center coordinate value, angle value, area value, and true position value) of an image of the actual elongate slot and a monitor displays information corresponding to the actual and target values. The inspection device and method is primarily used to inspect slotted rings used in stators for gas turbine engines.
