Subprograms and program section repeats
If a machining sequence occurs several times in a program, you
can save time and reduce the chance of programming errors by
entering the sequence once and then defining it as a subprogram
or program section repeat. If you wish to execute a specific
program section only under certain conditions, you also define this
machining sequence as a subprogram. In addition, you can have a
part program call a separate program for execution.
"Subprograms and Program Section
Programming with Q parameters
Instead of programming numerical values in a machining program,
you enter markers called Q parameters. You assign the values to
the Q parameters separately with the Q parameter functions. You
can use the Q parameters for programming mathematical functions
that control program execution or describe a contour.
In addition, programming with Q parameters enables you to
measure with the 3-D touch probe during the program run.
