ABSTRACT:
A method and apparatus for forming patterns from sheet material employs a castered cutting bit that is guided along a closed cutting path defined by the shape of the desired pattern. The bit is mounted fixedly in a presser foot and projects a predetermined amount below the surface of the foot to control the depth of cut into the material. Frangible materials are cut to depth less than the thickness of the material, and thereafter complete severance of the pattern from the sheet material is accomplished by fracturing the material along the line of cut.
