Multipoint tools
A multipoint tool is a tool with multiple cutting edges or multiple
reference points. A data record is created for every cutting edge or
every reference mark. Then all data records of the multipoint tool are
linked together.
For every data record of a multipoint tool, the position within the
multipoint tool chain is shown in the tool list in the column "MU."
Counting begins with byte “0.”
The figure at right shows a tool with two reference points.
Tool life management
The control can "count" either the machining time of a tool (i.e. the time
a tool is traversed at the programmed feed rate) or the number of parts
that were produced with that tool. These two options are used for tool
life management.
As soon as the tool life expires or the programmed quantity is reached,
the system interrupts machining and asks you to replace the tool or
cutting edge. The machining operation, however, is not interrupted
until the workpiece that is currently being produced is finished.
