Abstract: A panel cutter has a clamping mechanism positioned adjacent to the cutting path to hold the panel material in position during the cutting process. The clamping mechanism includes a clamping bar which is removably coupled to a pair of lever mechanisms which are rotatably coupled to the framework of the panel cutter. An actuator bar having cams at both ends is also coupled to the framework and position adjacent to the lever arms, wherein movement of the actuator bar causes movement of the lever arms. Based upon the configuration and positioning of these components, movement of the lever arms causes the clamping bar to move between a locked position and an unlocked position.

Abstract: There is provided a knife attachment that is interchangeable with a saw attachment for a sheet cutting system. The knife attachment has a base plate to which is attached a cutting head that carries a blade holder. The blade holder is adjustable for depth penetration as well as for angle of approach to the work piece.
