A woodworking machine for cutting a plurality of oriented Vgrooves in a wood panel to effect simple cabinet fabrication. The grooves are formed by a cutting assembly having a pair of rotary cutters disposed at 45* with respect to the table and at 90* with respect to each other. The cutters have intermeshed teeth and are synchronously driven by a single electric motor through a gear transmission. The cutter assembly is carried on a track supported by an overhead frame and is arranged to pass over the wooden panel in cutting relation, which rests on a horizontal table. The machine includes means for lowering the cutting assembly to a desired position above the table and advancing the assembly with respect to the panel to form the groove. The cutting assembly is then elevated to a non-cutting position and returned to its initial position.
