Assign touch probe axis to machine axis for a measuring touch probe (not TNC 410)

MP6322.0
Machine X axis parallel to touch probe axis X: 0, Y: 1, Z: 2

MP6322.1
Machine Y axis parallel to touch probe axis X: 0, Y: 1, Z: 2

MP6322.2
Machine Z axis parallel to touch probe axis X: 0, Y: 1, Z: 2

Maximum stylus deflection of the measuring touch probe (not TNC 410)

MP6330
0.1
to 4.0000 [mm]

Feed rate for positioning measuring touch probes at MIN point and approaching the contour (not TNC 410)

MP6350
10
to 3 000 [mm/min]

Probe rate for measuring touch probe (not TNC 410)

MP6360
10
to 3 000 [mm/min]

Rapid traverse for measuring touch probes in the probe cycle (not TNC 410)

MP6361
10
to 3 000 [mm/min]

Feed rate reduction when the stylus of a measuring touch probe is deflected to the side (not TNC 410)

The TNC decreases the feed rate according to a
preset characteristic curve. The minimum input
value is 10% of the programmed digitizing feed
rate.

MP6362
Feed rate reduction not active: 0
Feed rate reduction active: 1

Radial acceleration during digitizing for measuring touch probe (not TNC 410)

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.

MP6370
0.001
to 5.000 [m/s

2

] (recommended input value: 0.1)

Ensure that the touch probe axes are
correctly assigned to the machine axes.
Wrong assignment could lead to a
stylus break.
