Abstract
Abstract A woodworking machine is disclosed that forms a plurality of properly oriented grooves in a wood panel to effect simple cabinet fabrication. The panel rests on a horizontal table having an alighment fence and a plurality of selective operable stops that enable placement of the panel on the table in a plurality of predetermined grooving positions. A clamping device holds the panel in one of the positions, and a groove is then formed by a cutting assembly including a pair of rotary cutters both of which are disposed at 45* with respect to the table and at 90* with respect to each other. 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 assembly is then elevated to a non-cutting position and returned to its initial position. The machine also includes means for automatically actuating the stops in a preselected sequence to effect the formation of a plurality of properly placed grooves.
