Abstract
In an automatic sawing machine wherein a workpiece is moved in two orthogonal directions by a profile control or a numerical control so as to cut a groove of a predetermined profile, the opposite ends of the fret saw blade are synchronously driven by independent pulse motors so as to direct the fret saw blade always in the tangential direction of the profile.
