Assign touch probe axis to machine axis for
a measuring touch probe
Note:
Ensure that the touch probe axes are correctly
assigned to the machine axes. Wrong
assignment could lead to a stylus break.

probes at MIN point and approaching the

Feed rate reduction when the stylus of a
measuring touch probe is deflected to the
side
The TNC decreases the feed rate according to
a preset characteristic curve. The minimum
input value is 10% of the programmed
digitizing feed rate.

Feed rate reduction not active: 0

Radial acceleration during digitizing with
the measuring touch probe
MP6370 enables you to limit the feed rate of
the TNC for circular movements during
digitizing. Circular movements are caused, for
example, by sharp changes of direction.
As long as the programmed digitizing feed rate
is less than the feed rate calculated with
MP6370, the TNC will move at the
programmed feed rate. Determine the
appropriate value for your requirements by trial
and error.

Target window for digitizing contour lines
with a measuring touch probe
When you are digitizing contour lines the
individual contour lines do not end exactly in
their starting points.
With machine parameter MP6390 you can
define a square target window within which
the end point must lie after the touch probe has
orbited the model. Enter half the side length of
the target window for the side length.
