URE ANGLE (Cy
cle 420, DIN/ISO:
G420)
 Traverse direction 1
Q267: Direction in which the
probe is to approach the workpiece:
–1 :Negative traverse direction
+1 : Positive traverse direction
 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 MP6140. Input range 0 to 99999.9999,
alternatively PREDEF
 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
 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
 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 program run and display the measuring
log on the screen. Resume program run with NC
Start.
