Tool life management allows you to limit the use of a tool and automatically switch to another tool when that limit is reached. It is useful when cutting hard material that may wear out a tool during a single program run. The tool mapping dialog box displays the number of holes that will be cut by each drilling tool and the number of minutes that each milling tool will be used during a single run of the NC program.
To specify tool life information for a tool:
Select the tool in the tool mapping dialog box.
Click the Tool life button.
The Tool life dialog box is displayed.
