5.2.3.4 Overcut
The pre-cut x
1
is the distance from the centre of the axis of rotation to the first point where the cutting
edge cuts the material surface in the direction of travel. The post-cut x
2
is the measurement from the
centre of the axis of rotation to the last point where the cutting edge cuts the material surface.
The cutting angle has the greatest influence on processing quality. A narrower cutting angle may
enable a faster processing speed, but it also produces a greater overcut. A narrower cutting angle can
be used for paths that include large curves and long straight sections.
Tip:
The overcut distorts the cutting paths. For cuts with a low margin of error, Zünd recommends
choosing a knife with a lower overcut. Overcut information can be found in the additional
specifications for each knife.

5.2.3.4.1 Calculating the overcut
Depending on the cutting depth, the blade geometry will produce a different level of overcut. This
chapter explains how to calculate your overcut based on the blade you are using and the material you
are cutting. The Z20 pointed oscillating knife and Z11 drag knife are used as examples here.
The cutting depth TM is made up of the material thickness t and the set depth z. Insert these values
into the formula as they are listed in the product description for each blade. The result will be the pre-
cut/post-cut in mm.
