Claims
- 1. A method of producing scored panels from panels having front and back faces and having a minimum thickness along some locations and a maximum thickness along other locations, including cutting grooves in said front face having an inner wall and radiused corners along each side of said inner wall, providing a groove depth along said inner wall with an inner extremity spaced a uniform distance from said back face sufficient to maintain required panel strength, providing said radiused corners with a radius of curvature less than one-half said minimum thickness and edges remote from said inner surface extending substantially perpendicular to said back face and spaced therefrom by a distance substantially equal to said minimum thickness, and providing said grooves with a surface extending substantially perpendicular to said faces from said edges to said front face along portions of said panel having a thickness greater than said minimum thickness.
- 2. A method as set forth in claim 1, including forming said inner surface with a radius of curvature substantially greater than said maximum thickness.
- 3. A method as set forth in claim 2, including forming said inner surface so that said inner extremity thereof is spaced from said back face by a distance exceeding one-half said minimum thickness of said panel.
- 4. A method as set forth in claim 3, including cutting said grooves in said front face with cutters having cutter teeth contoured to conform to the contour of said grooves.
