Abstract
A cutting apparatus comprises a frame assembly which includes a support surface and a first cutting blade. The cutting apparatus also comprises a cutting arm assembly which is rotatably attached to the frame assembly and includes a second cutting blade. The cutting apparatus also comprises an alignment mechanism secured to the frame assembly and the cutting arm assembly.
Claims20
A cutting apparatus comprising:
- a frame assembly including a support surface and a first cutting blade;
- a cutting arm assembly rotatably attached to the frame assembly, the cutting arm including a second cutting blade;
- an alignment mechanism secured to the frame assembly and the cutting arm assembly, wherein the alignment mechanism includes an alignment block, a first biasing member having a first bolt having a first longitudinal axis passing through the alignment block and a first spring with a first adjustable tension, and a second biasing member having a second bolt having a second longitudinal axis passing through the alignment block and a second spring with a second adjustable tension, wherein the first bolt and the second bolt are substantially perpendicular to each other, and further wherein the position of the cutting arm assembly is rotatable relative to the first cutting blade about an axis perpendicular to both the first and second longitudinal axes by adjusting at least one of the first tension, the second tension, or a combination of the first and second tensions.
A method for cutting a sheet member comprising the steps of:
- providing a cutting apparatus including
- a frame assembly including a support surface and a first cutting blade,
- a guide fence selectively attachable to the support surface such that the position of the guide fence corresponds to a cut width and an angular degree,
- a cutting arm assembly rotatably attached to the frame assembly, the cutting arm including a second cutting blade,
- an alignment mechanism secured to the frame assembly and the cutting arm assembly, wherein the alignment mechanism includes an alignment block, a first biasing member having a first bolt having a first longitudinal axis passing through the alignment block and a first spring with a first adjustable tension, and a second biasing member having a second bolt having a second longitudinal axis passing through the alignment block and a second spring with a second adjustable tension, wherein the first bolt and the second bolt are substantially perpendicular to each other, and further wherein the position of the cutting arm assembly is rotatable relative to the first cutting blade about an axis perpendicular to both the first and second longitudinal axes by adjusting at least one of the first tension, the second tension, or a combination of the first and second tensions,
- adjusting the position of the guide fence to correspond to a predetermined cut width and a predetermined angular degree;
- aligning a sheet member on the support surface with the guide fence;
- and
- cutting the sheet member to the desired shape.
