Abstract
A workpiece cutting method basically includes providing a workpiece proximate to a first blade including a first cutting edge. The method further comprises moving a second blade including a second cutting edge in contact with the first blade such that the first and second cutting edges of the first and second blades cooperatively engage to cut the workpiece while maintaining the first and second cutting edges parallel to each other.
Claims16
A workpiece cutting method comprising:
- providing a workpiece proximate to a first blade including a first cutting edge;
- and
- moving a second blade including a second cutting edge and a guide section having a slanted surface in contact with the first blade such that the slanted surface of the second blade contacts and slides against the first blade to adjust a position of the second blade before the first and second edges contact each other to eliminate a gap between the first and second edges and such that the first and second cutting edges of the first and second blades cooperatively engage to cut the workpiece while maintaining the first and second cutting edges parallel to each other.
A workpiece cutting apparatus comprising:
- a stationary plate including a first blade having a first cutting edge;
- a moving plate facing opposite the stationary plate and configured to move toward the stationary plate;
- a moveable component that is disposed on a surface of the moving plate that faces the stationary plate, the moveable component being moveable along a plane of the surface and including a second blade having a second cutting edge, the second blade including a guide section having a slanted surface;
- and
- a pressing component configured to press the moveable component toward the first blade at least when the moving plate moves toward the stationary plate such that the first and second blades contact each other, the pressing component being further configured to continue to press the moveable component toward the first blade to maintain the first and second cutting edges parallel to each other while the first and second blades cooperatively engage to cut the workpiece, the slanted surface of the second blade being configured to contact and slide against the first blade and to adjust a position of the second blade before the first and second edges contact each other to eliminate a gap between the first and second edges.
