TNC 640 | User's Manual Cycle Programming | 3/2014
457
Datum number in table Q305: Enter the number in
the datum/preset table in which the TNC is to save
the coordinates of the pocket center. If you enter
Q305=0, the TNC automatically sets the display so
that the new datum is at the center of the pocket.
Input range 0 to 2999
New datum for reference axis Q331 (absolute):
Coordinate in the reference axis at which the TNC
should set the pocket 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 pocket 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",
page 438)
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 = 1. 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
Probe TS axis: Coord. 3rd axis Q384 (absolute):
Coordinate of the probe point in the touch probe
axis, 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
