DATUM CIRCLE CENTER (Cycle 416, DIN/ISO: G416, software
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 322)
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
New datum in TS axis Q333 (absolute): Coordinate
in the touch probe axis at which the TNC should
set the datum. Default setting = 0. Input range
-99999.9999 to 99999.9999
Set-up clearance Q320 (incremental): Additional
distance between measuring point and ball tip.
Q320 is added to SET_UP (touch probe table), and
is only effective when the datum is probed in the
touch probe axis. Input range 0 to 99999.9999
