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.
