Programming AFC
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 PROGRAM FUNCTIONS 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:
Besides the data from the AFC.TAB table, the control also saves
the following additional information in the <name>.H.AFC.DEP file:
