TNC 640 | User's Manual Cycle Programming | 1/2015
Execute basic rotation Q304: Definition of
whether the TNC should compensate workpiece
misalignment with a basic rotation:
0
: Do not execute basic rotation
1
: Execute basic rotation
Datum number in table Q305: Enter the datum
number in the datum or preset table in which
the TNC is to save the coordinates of the corner.
If Q303=1: If you enter Q305=0, the TNC
automatically sets the display so that the new
datum is on the corner. If Q303=0: If you enter
Q305=0, the TNC writes to line 0 of the datum
table. Input range 0 to 99999
New datum for reference axis Q331 (absolute):
Coordinate in the reference axis at which the TNC
should set the corner. 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 calculated corner. 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
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
