Abstract
A system is provided for detecting or locating an edge of a workpiece in a processing path. The system includes a reflector which can be positioned at an elevation higher than the workpiece in the processing path. According to one aspect of the invention, the reflector can be mounted in a recess of a clamp which can be moved to engage the workpiece. The system also includes a light beam source and reflected light beam sensor located along one side of the processing path. According to another aspect of the invention, the light beam can be directed at an oblique angle through a corner of the processing path to the reflector. Interruption of the light beam changes the state of the sensor which indicates the location of the workpiece edge relative to the location of the light beam source along one axis of a mutually orthogonal three-axis coordinate system.
