13.04 Determining Settings for Cutting a New Material
The following subsections present a recommended method for determining the best settings for cutting. While
you may be tempted to use a “trial and error” process, this can lead to damaging the Force if the bit ends up
going too deep and gouging the cutter!
13.04.1 Measure the Thickness of the Material
•
Manufacturers will often round up the actual thickness of a material and report that higher number on the
packaging or even in the specs. Thus,
it’s important to determine the true thickness as accurately as
possible.
You can measure the material in mm or in inches. The online calculator is set up for either.
If you own a caliper, then measure in several locations and then plan to enter an average value into the
online calculator.
If you do not own a caliper, then measure to the best of your ability using a ruler with small increments.
•
Don’t fret if you feel the measurement isn’t precise. The
PenTest
presented in
Section 13.05
will help you
adjust the
CD/ED
setting so that you won’t cut through the mat.
13.04.2 Surface Height

The
Surface Height (SH)
is a specific location where the head will drop for setting the
Z Origin.
