Soft Paper Cutting Demonstration Video by Challenge

Watch the material ‘lift’ when under clamping force and you can see the same thing happening to the material in front of the knife. There are several things that you can do to help minimize the lifting.

First, you reduce the pile size. In this video example, they are using a 3″ pile of very thin, flimsy paper (phone book-like). They recommend under 2″ (as a starting point).

Secondly, set the backgauge to fixed dimension in this case, it is set to 1-1/2″.

Reduce the clamping pressure to the minimum setting and cut your strips one at a time  and set them aside. Doing this maintains a solid surface that is completely holding flat virtually all of the material while cutting.

Now you can reposition the backgauge (if necessary) to the next dimension. In this case, they left it at 1-1/2″. If you watch closely you can see that the paper is not firmly held flat.

Following these suggestions should help increase your final product quality.
