16.5 MEASURE HOLE (Cycle 421, DIN/ISO: G421)
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 TCHPR421.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.
U 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
U Tool for monitoring Q330: Definition of whether the
TNC is to monitor the tool (see “Tool monitoring” on
page 400). Input range: 0 to 32767.9, alternatively tool
name with max. 16 characters
0: Monitoring not active
>0: Tool number in the tool table TOOL.T
U No. of measuring points (4/3) Q423: Specify
whether the TNC should measure the stud with 4 or
3 probing points:
4: Use 4 measuring points (standard setting)
3: Use 3 measuring points
U Type of traverse? Line=0/Arc=1 Q365: Definition of
the path function with which the tool is to move
between the measuring points if “traverse to
clearance height” (Q301=1) is active.
0: Move between operations on a straight line
1: Move between operations on the pitch circle
