You can teach any number of machining steps for
a tool. Your machine tool builder will either make
a function available for this, or will integrate this
possibility in the functions for switching on the
spindle. Refer to your machine manual.

You machine tool builder can provide a feature
with which the teach-in cut can be automatically
ended after a selectable time. Refer to your machine
manual.

In addition, your machine tool builder can integrate
a function with which you can directly enter the
reference power of the spindle, if it is known. In this
case a teach-in step is not required.

The functions for starting and ending a machining
step are machine-dependent. Refer to your machine
manual.

Proceed as follows to select and, if required, edit the
.H.AFC.DEP file:

Select the

Program Run, Full Sequence operating
