A cutting apparatus for forming a V-sectioned groove in a workpiece includes a support surface, a pair of guide rails mounted in parallel relationship with one another and in relatively low relationship with the support surface and a platform mounted upon the guide rails for movement relative to and along the length of the rails. The apparatus further includes a cutter carried by the platform for movement therewith relative to and along the length of the guide rails and including a tipped rotatable cutting tool. The cutter is supported by the platform so that the rotational axis of the cutting tool is oriented generally perpendicular to the support surface and so that the tip thereof is placed relatively close to the support surface. The cutter is adapted to form a V-sectioned groove in a workpiece positioned upon the support surface as the cutting tool is rotated and moved in cutting engagement with the workpiece and as the cutter and platform are moved relative to and along the guide rails. When the apparatus is used to form a groove in a workpiece of the type having a relatively rigid substrate and a cladding of flexible material layered upon one side of the workpiece opposite the groove-side thereof, the flexible material remains intact after the groove is formed and accommodates a folding of the workpiece about the formed groove so that the corner formed by the fold appears unbroken. The apparatus also includes a fence system and hold-down devices which facilitate mass production of grooved workpieces of like construction.
