Abstract
A cutting device (10) for cutting sheet material (14) is provided and comprises a circular cutting tool (40) including a blade (42) extending along the circumference thereof. A support structure (18) supports the sheet material (14). A cutting tool support (46) is provided for supporting the circular cutting tool (40) such that the circular cutting tool (40) freely rotates within the support (46) to thereby rotate on the surface of the sheet material (14) when the blade (42) contacts the sheet material (14). A drive mechanism (50) is interconnected to the cutting tool support (46) for imparting a vertical force to the cutting tool (40) for moving the blade into cutting engagement with the sheet material (14) to thereby cut the sheet material (14) with minimal vertical displacement of the circular cutting tool (40) during the cutting operation.
