Cycle parameters
Starting point in 1st axis Q328 (absolute): Starting
point for probing in the reference axis of the working
plane. Input range -99999.9999 to 99999.9999
Starting point in 2nd axis Q329 (absolute): Starting
point for probing in the minor axis of the working
plane. Input range -99999.9999 to 99999.9999
Offset for 2nd measurement Q310 (incremental):
Distance by which the touch probe is displaced
before the second measurement. If you enter 0, the
TNC does not offset the touch probe. Input range
-99999.9999 to 99999.9999
Measuring axis Q272: Axis in the working plane in
which the measurement is to be made:
1 : Principal axis = measuring axis
2 : Secondary axis = measuring axis
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
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
Nominal length Q311: Nominal value of the length
to be measured. Input range 0 to 99999.9999
Maximum dimension Q288: Maximum permissible
length. Input range 0 to 99999.9999
Minimum dimension Q289: Minimum permissible
length. Input range 0 to 99999.9999
Measuring log Q281: Define whether the TNC
should create a measuring log:
0 : Do not create a measuring log
1 : Create a measuring log: The TNC saves the log
file TCHPR425.TXT as standard in the directory
TNC:\.
2 : Interrupt program run and output measuring log
to the TNC screen. Resume program run with NC
Start.
PGM stop if tolerance error Q309: Definition of
whether in the event of a violation of tolerance
limits the TNC is to interrupt program run and output
an error message:
0 : Do not interrupt program run, do not output an
error message
1 : Interrupt program run and output an error
message
