Abstract
A cutting apparatus employs a cutting wheel which is rotated about an axis perpendicular to a support surface on which sheet material is positioned for cutting. A stripping plate is mounted in closely spaced relationship with the cutting wheel so that shredded material generated by the wheel during a cutting operation is sheared off. The cutting wheel in a cutting operation is advanced relative to the sheet material so that the leading cutting edges of the wheel, rather than the trailing edges, move along the desired line of cut. The material being cut is positioned on a bed that can be penetrated by the wheel and the depth of penetration of the wheel into the bed is regulated to remain substantially constant as the tool moves along the line of cut.
Claims14
Apparatus for cutting a workpiece such as sheet material comprising:
- support means defining a support surface on which the workpiece may be placed during a cutting operation;
- a cutting tool positioned over the support surface for cutting the workpiece, the tool including a cutting wheel having cutting edges arranged coaxially of an axis of rotation located in perpendicular relationship to the support surface and a stripping member arranged coaxially of the wheel and in cooperating close-fitting relationship with the cutting edges to shear chips being cut from the workpiece;
- and
- controlled drive means connected with the support means and the tool for translating the tool and the workpiece relative to one another parallel to the work surface to advance the tool through the workpiece along a desired line of cut.
