HIGH SPEED DRILL BIT QUALITY AND POSITION CONTROL

摘要

This invention relates to the monitoring of drill bits between drill strokes in automatic drill machines, typically of a high capacity multiple spindle type used for drilling printed circuit boards. It provides a solution that allows inspection of all bits in such drill machines between each drill stroke, without reduction of machine performance in normal production drilling. This invention applies video cameras suitably mounted with optical fibers or other light deflecting accessories, adapted to provide instant means values of light intensities to a computer system to determine drill bit geometry.
