444 Programming: Special Functions
11.6 Adaptive Feed Control (AFC—software option)
Each line in the <name>.H.AFC.DEP file stands for a machining section,
which 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 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 441), the TNC saves the following additional information in the
<name>.H.AFC.DEP file:
Column Function
NR Number of the machining step
TOOL Number or name of the tool with which the machining
step was made (not editable)
IDX Index of the tool with which the machining step was
performed (not editable)
N Difference for tool call:
0: Tool was called by its tool number
1: Tool was called by its tool name
PREF Reference load of the spindle. The TNC measures the
value in percent with respect to the rated power of the
spindle
ST Status of the machining step:
L: In the next program run, a teach-in cut is recorded
for this machining step. The TNC overwrites any
existing values in this line
C: The teach-in cut was completed successfully. The
next program run can be conducted with automatic
feed control
