HEIDENHAIN iTNC 530 443
11.6 Adaptive Feed Control (AFC—software option)
Recording a teach-in cut
The TNC provides several cycles that enable you start and stop a
teach-in step:
FUNCTION AFC CUT BEGIN TIME1 DIST2 LOAD3: The TNC starts a
sequence of cuts with active AFC. The switch from the teach-in cut
to closed-loop mode begins as soon as the reference load was
determined in the teach-in phase, or once one of the conditions
TIME, DIST, or LOAD is fulfilled. With TIME you define the maximum
duration in seconds of the teach-in phase. DIST defines the
maximum distance for the teach-in cut. With LOAD you can set a
reference load directly. The entries in TIME, DIST, and LOAD are
modally effective. You can reset the respective function by
programming it again with the value 0.
FUNCTION AFC CUT END: The AFC CUT END function deactivates AFC
control
FUNCTION AFC CTRL: The function AFC CTRL activates closed-loop
mode starting with this block, even if the learning phase has not
been completed yet.
To program the AFC functions for starting and ending the teach in cut,
proceed as follows:
In the Programming 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 TNC firstly copies the basic settings defined in
the AFC.TAB table into the file <name>.H.AFC.DEP for each machining
step. <name> is the name of the NC program for which you have
recorded the teach-in cut. In addition, the TNC measures the
maximum spindle power consumed during the teach-in cut and saves
this value in the table.
