ABSTRACT:
Method and machine for cutting by automatic band saw wherein the workpiece is machined in such a manner that the machining tracks of the workpiece describe circular arcs and the cutting edge of the band saw contacts only part of the workpiece to prevent generation of loadings between the teeth of the saw. The oscillating body in which the band saw is housed is held capably of performing oscillating and tilting motions in the left and right and upward-and-downward motions and the band saw descends, performing oscillating and tilting motions, or the latter performs alternately the oscillating and tilting motions with the descending motions repeatedly, to cut the workpiece. Either a crank mechanism or a hydraulic cylinder is used for driving the oscillating and tilting motions, and a hydraulic cylinder and a cam mechanism are used for driving the upward and downward motions.
