5.4 ShopMill tool management
The pre-warning limit specifies the tool life, workpiece count or wear
at which the first warning is displayed.
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 (left and
right adjacent location) 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 the "Tool wear" softkey.
Position the cursor on the tool that you want to monitor.
In the column "T/C" select the parameter that you wish to monitor (T =
Tool life, C = Count, W = Wear).
Enter a pre-warning limit for tool life, count or wear.
Enter the scheduled service life for the tool, the scheduled number of
workpieces to be machined or the maximum permissible wear.
The tool is disabled when the tool life, count or wear is reached.
Select the "Tool wear" softkey
Place the cursor on a tool.
Select the option "G" in the first field of the last column if you want to
disable the tool for machining.
Select the option "U" in the second field of the last column if you want
to mark the tool as oversize.
