"Alternat." softkey and toggle key:
If the cursor is positioned on an input field with various setting options,
the "Alternat." softkey is automatically displayed on the vertical
softkey bar (see "Alternat." softkey in Sec. "Important softkeys for
operation and programming").
Roughing/finishing:
Every cycle can be programmed with roughing or finishing. If you wish
to rough cut the workpiece first and then finish cut it, you must call the
cycle a second time. The programmed values do not change if you
call the cycle again.
Some cycles offer roughing and finishing as a
complete machining
operation, i.e. you need only call the cycle once.
