Replacement tools
During "simple" tool life monitoring the control stops program run
when a tool is worn out. However, the program run is then resumed
and concluded.
If you use the tool life monitoring with replacement tools function,
the Steuerung automatically inserts the "sister tool" as soon as the tool
is worn out. The Steuerung does not stop the program run until the
last tool of the tool sequence of exchange is worn out.
You can define replacement tools when setting up the turret. The
"interchange chain" can contain more than one replacement tool. The
interchange chain is a part of the NC program.
In the T commands, you program the first tool to be changed.
Defining replacement tools
Place the cursor on the previous tool and press RETURN.
Enter the identification number of the replacement tool (Tool dialog
box) and define the replacement strategy.
When using multipoint tools, you define in the replacement strategy
whether the complete multipoint tool or only the worn-out cutting
edge of the tool is to be replaced by a replacement tool:
 0: Complete tool (default): If a cutting edge of the multipoint tool is
worn out, the tool will no longer be used.
 1: Secondary cutting edge or any: Only the worn-out cutting edge of
the multipoint tool is replaced by another tool or another cutting
edge. Any other cutting edges of the multipoint tool that are not
worn out will continue to be used.
