With the count C, the number of workpieces machined by the tool is
counted. The tool is also disabled in this case, when the remainder
reaches "0".
With wear W, the greatest value in the wear parameters ∆ Length X,
∆ Length Z or ∆ Radius or ∆ ∅ in the wear list is monitored. Here too
the tool is disabled if one of the wear parameters reaches the value
for wear W.
Please follow the machine manufacturer's instructions!
The pre-warning limit specifies a tool life or quantity at which an initial
warning is output.
Individual tools can also be disabled manually if you no longer want to
use them for workpiece machining.
In the case of oversize tools, neighboring magazine locations are only
reserved alternately, i.e. you can only insert the next tool in the next
magazine location but one (this can also contain an oversize tool).
You can assign tools a fixed location, i.e., the tool can only be used at
the current magazine location. The tool returns to the old magazine
location when switching back.
Select "Tool wear" via softkey
Position the cursor on the tool that you want to monitor.
