Abstract
An automatic saw is provided having a rotatable saw blade for cutting through a workpiece which is carried on a movable arm, which permits the workpiece to be moved into engagement with the saw blade. The saw blade is mounted on a first shaft while the workpiece and arm are mounted on a second, rotary shaft. Typically, a load cell is carried on the second shaft to sense torsional stress created by the pressure of the saw against the workpiece. This torsional stress is a direct measurement of the pressure of the saw against the load cell, and may be used in a feedback system for automatic adjustment of the sawing conditions. Also, it is preferred for the second shaft to be longitudinally movable in an automatic manner by means of a threaded, rotary arrangement for longitudinally advancing and retracting the second shaft between predetermined positions. A rotary encoder may be used to monitor the rotary position of the second shaft and arm.
