Abstract
Abstract The automated saw has a saw table and saw superposed over the table for movement there across at selected angles. Board-lengthpositioning devices are spaced along the saw table. The variable angle saw and the variable-length-positioning devices are controlled by an input including predetermined numerical information. The saw is set up that single and double cuts can be made at opposite ends of the boards with the board length and saw angle positioning devices being automatically preset by the numerical information input.
