摘要
The combination opposed helix router having an opposed helix 70 degree left-hand upper portion and a lower portion consisting of a 45 degree helix. The combination opposed helix router is utilized for edge trimming and preparing holes in composite material face sheets with honeycomb core wherein the left-hand helix forces the face sheet fibers downward, thereby shearing them off, while the right-hand, or lower portion, forces the fibers on the lower surface upward, thereby shearing them off which operation eliminates the heavy burr normally present on the outer surface of the honeycomb sandwich during conventional routing.
