12.6 Tool wear

12.6 Tool wear
All parameters and functions that are required during operation are contained in the tool
wear list.
Tools that are in use for long periods are subject to wear. You can measure this wear and
enter it in the tool wear list. The controller then takes this information into account when
calculating the tool length or radius compensation. This ensures a consistent level of
accuracy during workpiece machining.
You can automatically monitor the tools' working times via the workpiece count, tool life or
wear.
In addition, you can disable tools when you no longer wish to use them.
