    摘要： This invention is directed to a planar type of machine tool in which a plurality of cutting tools are individually mounted on the respective links of continuously driven endless chain that is bodily oscillatable about an axis transverse to the path of travel of the workpiece so that the cutting tools on one flight of the chain engage the workpiece during one direction of travel thereof and the cutting tools on the other flight of the chain engage the workpiece during its opposite direction of travel. The workpiece is progressively pivoted in one direction as it is advanced and progressively pivoted in the opposite directions as it is returned so that the tool cuts will be in straight lines substantially parallel to the sides of the workpiece.
