ABSTRACT:
Flat multi-layered work pieces, such as panels with a decorative or finish surface coating (5), are prescored and cut through by the same saw blade to avoid damage to the surface coating. For this purpose a circular saw (1) is guided along a guide rail (7) and its saw blade (4) is adjustable to a prescoring depth and to at least one lateral prescoring position to make a first prescoring cut only through the cover layer (5) in a sawing direction in synchronism with the blade rotation direction. If necessary, the blade is adjusted to a second lateral prescoring position to make a second prescoring cut only through the cover layer (5) in a cutting direction in synchronism with the blade rotation. Finally, the saw blade (4) is adjusted to its full cutting depth and to a lateral position between the two prescoring positions and a full cut is made through the entire work piece (6) in a sawing direction counter to the rotation direction of the saw blade. A circular saw for carrying out the foregoing method has a single saw blade, stop elements, and adjustment mechanism for adjusting the single saw blade into the various necessary positions. The prescoring avoids damage to the surface coating even if it is brittle.
