Furthermore, the starting position (angle) of the cutter should also be considered by the number of
cutters on the cutting axis. If the total pulses of cutting axis can be equally divided by the cutters, i.e.
even number of cutters shares even number of pulses, the pulses required for single cutter can be
obtained. Convert the obtained pulses into degrees and the starting position as well as the end position
can be obtained, which are the required parameters for setting thick material cutting. On the other hand,
if the total pulses of cutting axis can not be equally divided by the cutters, i.e. even number of pulses for
odd number of cutters, angle θ and the length of Master before sync area for single cutter should be set
up respectively to obtain the starting and end position of each cutter.
Also, care should be taken on setting the contact angle, which is related to the thickness of the material
and the vertical position of the cutting device. When setting the contact angle, make sure the contact
angle is a little smaller or equal to the actual contact angle otherwise an arc cutting plane will be
generated. On the other hand, the sync end angle should also be a little bigger or equal to the actual
sync end angle for ensuring that a smooth and flat cutting plane can be obtained.
 Pulses can be equally divided.
For even number of cutters, select “Equally divide non-sync area” function by bit0 of Data 1, and
DVP-20PM will automatically calculate the required pulses for each cutter. As the below diagram, in
actual settings only 2 parameters including “Sync start angle” and Sync end angle” are required for
calculating the angle of sync area α and the angle of non-sync area θ.
