Measuring height in the touch probe axis Q261
(absolute): Coordinate of the ball tip center (=
touch point) in the touch probe axis in which
the measurement is to be made. Input range
-99999.9999 to 99999.9999
Clearance height Q260 (absolute): Coordinate in
the touch probe axis at which no collision between
touch probe and workpiece (fixtures) can occur.
Input range -99999.9999 to 99999.9999
Datum number in table Q305: Enter the number
in the datum or preset table in which the TNC is to
save the coordinates of the bolt-hole circle center. If
you enter Q305=0, the TNC automatically sets the
display so that the new datum is on the bolt hole
center. Input range 0 to 2999
New datum for reference axis Q331 (absolute):
Coordinate in the reference axis at which the TNC
should set the bolt-hole center. Default setting = 0
input range -99999.9999 to 99999.9999
New datum for minor axis Q332 (absolute):
Coordinate in the minor axis at which the TNC
should set the bolt-hole center. Default setting = 0
input range -99999.9999 to 99999.9999
Measured-value transfer (0, 1) Q303: Specify
whether the determined datum is to be saved in the
datum table or in the preset table:
-1
: Do not use! Is entered by the TNC when old
programs are read in (See "Characteristics common
to all touch probe cycles for datum setting")
0
: Write determined datum in the active datum
table. The reference system is the active workpiece
coordinate system
1
: Write the measured datum into the preset table.
The reference system is the machine coordinate
system (REF system).
Probe in TS axis Q381: Specify whether the TNC
should also set the datum in the touch probe axis:
0
: Do not set the datum in the touch probe axis
1
: Set the datum in the touch probe axis
Probe TS axis: Coord. 1st axis Q382 (absolute):
Coordinate of the probe point in the reference axis
of the working plane at which point the datum is
to be set in the touch probe axis. Only effective if
Q381 = 1st input range -99999.9999 to 99999.9999
Probe TS axis: Coord. 2nd axis Q383 (absolute):
Coordinate of the probe point in the minor axis of
the working plane at which point the datum is to be
set in the touch probe axis. Only effective if Q381 =
1. Input range -99999.9999 to 99999.9999
