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
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
