ABSTRACT:
This invention can be attached to the head of a milling machine and performs the functions of a center scope and an edge finder. Unlike a center scope or an edge finder it does not have to be removed from the machine before the machine is used. The invention performs this function by processing images from two cameras that are shot from off axis vantage points. The two images are processed to create a synthetic image that appears to be shot from the on axis vantage point. The processor adds a cross hair to the image to indicate that point on the workpiece that is exactly at the center axis of the quill. This allows the machine operator to exactly position the spindle precisely over a target point on the workpiece in a convent and safe manner.
