To program the AFC functions for starting and ending the teach in
cut, proceed as follows:
In the
Programming
operating mode press the
SPEC FCT
key
Press the

soft key
Press the
FUNCTION AFC
soft key
Select the function
With a teach-in cut, the control at first copies the basic settings
for each machining step, as defined in the AFC.TAB table, to a
file called
<name>.H.AFC.DEP
.
<name>
is the name of the NC
program for which you have recorded the teach-in cut. In addition,
the control measures the maximum spindle power consumed
during the teach-in cut and saves this value in the table.
Each row in the
<name>.H.AFC.DEP
file stands for a machining
section, that you start with
FUNCTION AFC CUT BEGIN
and
complete with
FUNCTION AFC CUT END
. You can edit all data of
the
<name>.H.AFC.DEP
file for optimization purposes. If you have
optimized the values from the AFC.TAB table, the control places a
*
in front of these control settings in the AFC column.
Further information: "Defining basic AFC settings", page 538
Besides the data from the AFC.TAB table, the control also saves
the following additional information in the
<name>.H.AFC.DEP
file:
