摘要： A pressure foot assembly is provided which makes use of a pressure ring mounted in a manner which allows it to float laterally around an end mill cutter which is used to delete circuit lands on a subcomposite printed circuit panel. Enough pressure is provided to keep the ring from rotating and allows the ring to impart a concentrated force very close around the cutter, thus holding the deleted circuit line in place during cutting and keeping cutting burrs to a minimum.
