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. In addition, you can have a part program
call a separate program for execution.
Programming with subprograms and program section repeats:
see "Programming: Subprograms and program section repeats",
page 173.
Programming with Q parameters
Instead of programming numerical values in a part 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, parametric programming enables you to measure with
the 3-D touch probe during program run.
Programming with Q parameters: see " Programming: Q
Parameters", page 189.
