Measuring axis
Q272: Axis in the working plane in
which the measurement is to be made:
1: Reference axis = measuring axis
2: Minor 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.
Setup clearance
Q320 (incremental): Additional
distance between measuring point and ball tip. Q320
is added to MP6140.
Clearance height
Q260 (absolute): Coordinate in the
touch probe axis at which no collision between tool
and workpiece (fixtures) can occur.
Nominal length
Q311: Nominal value of the length to
be measured.
Maximum dimension
Q288: Maximum permissible
length.
Minimum dimension
Q289: Minimum permissible
length.
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 TCHPR426.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.
PGM stop if tolerance error
Q309: Definition of
whether in the event of a violation of tolerance limits
the TNC is to interrupt the program run and output an
error message:
0: Do not interrupt program run, no error message
1: Interrupt program run, output an error message
Tool number for monitoring
Q330: Definition of
whether the TNC is to monitor the tool (see “Tool
monitoring” on page 112)
0: Monitoring not active
>0: Tool number in the tool table TOOL.T
