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 control 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.

Selection of tool monitoring
- By tool life (T)
- By count (C)
- By wear (W)
The wear monitoring is configured via a machine data item.
Please refer to the machine manufacturer's instructions.
Setpoint for tool life, workpiece count, or wear
Specification of the tool life, workpiece count or wear at which a warning
is displayed.
The magazine location numbers.
The magazine number is specified first, followed by the location
number. Tools that are not assigned to a magazine in the tool list are
stored behind the magazine without a location number.
Spindle location as an icon.
