A chip removal method and apparatus for a sign engraving machine. The method involves engraving a sign blank in such a manner that chips fall from a cutting region on the sign blank into an enclosure, and swirling the chips in the enclosure so that the chips exhaust through an opening in the periphery of the enclosure and eventually pass through a chute into a receptacle. The apparatus is a guide member located parallel to an outer envelope of the volume that can be occupied by a rotating cutting head of the engraver. The guide member has a surface for contacting the sign blank. The contact surface has an access opening at its center to allow chips to enter the guide member from a cutting region on the sign blank. The guide member tapers away from the cutting region and has an exhaust opening and chute for exhausting the chips. The guide member is used with a rotating cutting head that propels chips circumferentially and allows them to be exhausted through the chute.
