ABSTRACT:
This relates to a workpiece particularly a simulated raised panel door as used on furniture and kitchen cabinets. Such doors are fabricated from a single sheet of core material and have a panel section machined into its face. In certain specific instances it is desired that the corners of the machined panel section be square and at best of very low radii. Because of this corner design it is virtually impossible and definitely time consuming to machine such corners in volume. The problem is solved by using preformed corner plugs inconjunction with a machined core. The core is composed of standard fiberboard material with a panel section machined into its face and plug housings machined into the face of the core at the panel section's proposed square corners. The corner plug is composed of a plastic material formed in part to that of a typical woodworking plug of cylindrical shape and a square inside corner section formed into the face and edge of the plug. Therefore, the square inside corner is formed by assembling the prefabricated corner plug into the plug housing of the core filling in the plug housing and completing the corner detail of the machined panel section.
