Tool life Threshold Percentage
A threshold level may also be assigned to a tool group. The threshold level
is assigned as a percentage of the total expected life of the tool. When a
tool reaches this threshold level, it is classified as old for that tool group.
A tool is classified as old only to allow the operator to see that a tool is
close to expiration. If the tool is being used when it reaches the threshold
level, it continues to be used as normal until the tool reaches the “expired
state” (100% of the expected tool life).
The tool life threshold percentage is selected on a per-group basis.
Different groups can use different threshold percentage, however each tool
in the group uses the same threshold percentage.
Entering Tool Group Data
To enter tool group data, you must create the tool groups. This is done
automatically when the group is selected to edit. To enter tools into groups
