Boundary conditions
• Block search
No program runtimes are determined through block searches.
• REPOS
The duration of a REPOS process is added to the current processing time ($AC_ACT_PROG_NET_TIME).
Examples
Example 1: Parameterization of the runtime measurement via MD27860
• Activating the runtime measurement for the active NC program and hence no measurement in case of active
dry run feedrate and program test:
MD27860 $MC_PROCESSTIMER_MODE = 'H2'
• Activating the measurement for the tool action time and measurement also with active dry run feedrate and
program test.
MD27860 $MC_PROCESSTIMER_MODE = 'H34'
• Activating the measurement for the total runtime and the processing time with an active tool, including
measurement with a program test:
MD27860 $MC_PROCESSTIMER_MODE = 'H25'
• Activating the measurement for the total runtime and the machining time (independent of the tool), including
measurement with a program test:
MD27860 $MC_PROCESSTIMER_MODE = 'Ha5'
• Activating the measurement for the processing time with an active tool, including measurements at an
override = 0%, but not with a trial run feed active:
MD27860 $MC_PROCESSTIMER_MODE = 'H22'
Example 2: Measuring the duration of "mySubProgrammA"
Program code
...
N50 DO $AC_PROG_NET_TIME_TRIGGER=2
N60 FOR ii= 0 TO 300
N70 mySubProgrammA
N80 DO $AC_PROG_NET_TIME_TRIGGER=1
N95 ENDFOR
N97 mySubProgrammB
N98 M30
After the program has processed line N80, the net runtime of "mySubProgrammA" is located in
$AC_OLD_PROG_NET_TIME.
The value from $AC_OLD_PROG_NET_TIME:
• is kept beyond M30.
• is updated each time the loop is run through.
