A work sheet support apparatus for greatly reducing and/or eliminating vaporized waste material deposits on a tooling plate during laser cutting of a work piece from various types of thin sheet material. The support apparatus allows for air flow in and around a newly cut surface in the work sheet. The air flow helps condense the vaporized material cut by a laser beam onto the sides of a plurality of holes in the support apparatus and preventing the waste material from depositing on the tooling plate. The apparatus includes a frame with one side having a scale corresponding to a "X" axis and an adjacent side having a scale corresponding to a "Y" axis. The support apparatus further includes a perforated housing, such as a honeycomb structure, having a plurality of holes therethrough for allowing air circulation in and around a newly cut surface of the work piece. The apparatus also includes legs on the bottom of corners of the frame for holding the apparatus above a flat surface of the tooling plate. The tooling plate is received on top of a work bench which can be raised and lowered vertically. Disposed on one side of the apparatus is an air stream discharge duct for circulating fresh air above and below the support apparatus. On an opposite side of the apparatus is a vacuum duct for receiving the circulated air along with air entrained particles from the laser cutting operation.
