ABSTRACT:
The method of cutting a plurality of boards or parts (20) from a number of stacked panels (10) which includes placing the panels upon a perforated fixture (2) including a plenum (14) such that the area beneath the perforated surface (4) may be evacuated. The stack of panels (10) are cut into boards or parts (20) the desired size and shape with the exception of a small tab (22) connecting each board or part (20) such that the entire panel (10) remains a unit. An impermeable sheet (24) such as plastic is placed over the top of the partially cut panels (10) and the space (14) beneath the partially cut panels is evacuated holding the parts in position. The tabs (22) are then cut and the boards or parts (20) removed.
