CHAPTER 5 : FINETUNING YOUR CUTTER

5.2 SETTING THE TOOL FORCE
Tool force (cutting pressure) is the amount of downward pressure that the cutter applies on the knife / pen.
We merely want to point out that you have to try to cut your design with the lowest possible pressure that
gives no trouble to weed. Some cast media require only 20 grams to be cut completely through. In that case
there is no need to apply 100 grams of pressure. Too much pressure can cause a decrease of quality.
For cutting through applications we recommend 250 grams. The same principle as for contour cutting, the
lowest possible pressure is advised, not only for the output quality but also for the lifetime of the cutting mat.
Notes
Please refer to the chapter “Direct key access” to know how to change the tool force.
5.3 OFFSET PRINCIPLE
One of the most important factors to obtain good quality, but unfortunately also one of the factors that is
easily forgotten, is the offset.
As you can see in the figure below, the knife offset (2) is the distance between the knife centre and the knife
tip.
1: Cutter blade
2: Theoretical Offset
Accurate measurement of the OFFSET to be used is very difficult and requires specialized equipment. You
should therefore adjust the offset (2) by checking real cutting results on the media you will use. MUTOH
helps you doing this by way of a semi-automatic offset adjustment routine, which has been integrated into
your cutter.
The selected Offset value is LARGER than the
optimum knife offset.
The selected Offset value is SMALLER than the
optimum knife offset.
In this case, a square corner will be cut as follows :
In this case, a square corner will be cut as follows :
The cutting direction is indicated by the arrow. The
corners are not well formed. The cutter cuts too far in
the angular points.
The cutting direction is indicated by the arrow. The
corners are not well formed. The cutter did not cut
far enough in the angular points.
Notes
Please refer to the chapter “Direct key access” to know how to change / test the offset value.
