TNC 320 | User's Manual Cycle Programming | 5/2013
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
Traversing to clearance height Q301: definition
of how the touch probe is to move between the
measuring points:
0
: Move at measuring height between measuring
points
1
: Move at clearance height between measuring
points
Datum number in table Q305: Enter the number
in the datum/preset table in which the TNC is to
save the coordinates of the stud center. If you enter
Q305=0, the TNC automatically sets the display
so that the new datum is on the stud 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 stud 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 stud 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
