HEIDENHAIN iTNC 530 407
16.4 MEASURE ANGLE (Cycle 420, DIN/ISO: G420)
U Traverse direction 1 Q267: Direction in which the
probe is to approach the workpiece:
-1: Negative traverse direction
+1: Positive traverse direction
U 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
U Setup clearance Q320 (incremental): Additional
distance between measuring point and ball tip. Q320
is added to MP6140. Input range 0 to 99999.9999,
alternatively PREDEF
U 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, alternatively PREDEF
U 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
Alternatively PREDEF
U Measuring log Q281: Definition of whether the TNC is
to create a measuring log:
0: No measuring log
1: Generate measuring log: with the standard setting
the TNC saves the log file TCHPR420.TXT in the
directory in which your measuring program is also
stored.
2: Interrupt the program run and display the
measuring log on the screen. Resume program run
with NC Start.
