option (AFC)
Each line in the .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 .H.AFC.DEP
file if you wish to optimize them. If you have optimized the values in
comparison with the values in the AFC.TAB table, the TNC places an
asterisk * in front of the control settings in the AFC column. Besides
the data from the AFC.TAB table (see "Defining the AFC basic settings"
on page 447), the TNC saves the following additional information in the
.H.AFC.DEP
file:
