Adaptive feed control (AFC) has the following advantages:
Optimization of machining time
By controlling the feed rate, the control tries to maintain the
previously recorded maximum spindle power or the reference
power specified in the tool table (
AFC-LOAD
column) during
the entire machining time. It shortens the machining time by
increasing the feed rate in machining zones with little material
removal.
Tool monitoring
If the spindle power exceeds the recorded or specified
maximum value (
AFC-LOAD
column of the tool table), the
control decreases the feed rate until the reference spindle
power is reached again. If the maximum spindle power is
exceeded during machining and at the same time the feed rate
falls below the minimum that you have defined, the control
reacts by shutting down. This helps to prevent further damage
after a tool breaks or is worn out.
Protection of the machine’s mechanical elements
Timely feed rate reduction and shutdown responses help to
avoid machine overload.
