Touch Probe Cycles: Automatic Datum Setting
15.9 DATUM FROM INSIDE OF CORNER (Cycle 415, DIN/ISO: G415,
software option 17)

Cycle parameters

1st meas. point 1st axis Q263 (absolute):
Coordinate of the first touch point in the reference
axis of the working plane. Input range -99999.9999
to 99999.9999
1st meas. point 2nd axis Q264 (absolute):
Coordinate of the first touch point in the minor axis
of the working plane. Input range -99999.9999 to
99999.9999
Spacing in 1st axis Q326 (incremental): Distance
between the first and second measuring points in
the reference axis of the working plane. Input range
0 to 99999.9999
Spacing in 2nd axis Q327 (incremental): Distance
between third and fourth measuring points in the
minor axis of the working plane. Input range 0 to
99999.9999
Corner Q308: Number identifying the corner which
the TNC is to set as datum. Input range 1 to 4
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
Set-up clearance Q320 (incremental): Additional
distance between measuring point and ball tip.
Q320 is added to SET_UP (touch probe table). Input
range 0 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
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
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
you enter Q305=0, the TNC automatically sets the
display so that the new datum is on the corner.
Input range 0 to 2999
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
