Tool wear monitoring
Activate cut-related tool wear monitoring by entering a value not
equal to 0 in the
AFC-OVLD1
column in the tool table.
The shutdown response depends on the
AFC.TAB
column
OVLD
.
In conjunction with cut-related tool wear monitoring the control
only evaluates the two options
M
and
L
in the
OVLD
column,
whereby the following responses are possible:
Pop-up window
Lock current tool
Insert replacement tool
If the
AFC.TAB
columns
FMIN
and
FMAX
each have a
value of 100%, adaptive feed control is deactivated but
cut-related tool wear monitoring remains active.

Tool load monitoring
Activate cut-related tool load monitoring (tool breakage control) by
entering a value not equal to 0 in the
AFC-OVLD2
column in the
tool table.
As shutdown response, the control always executes a machining
stop and locks the momentary tool.
If the
AFC.TAB
columns
FMIN
and
FMAX
each have a
value of 100%, adaptive feed control is deactivated but
cut-related tool load monitoring remains active.
