Tool life monitoring
If desired, you can have the CNC PILOT monitor tool life or the number
of parts that are produced with a specific tool.
The tool life monitoring function adds the time a tool is used at feed
rate. The quantity monitoring counts the number of finished parts. The
count is compared with the entry in the tool data.
As soon as the tool life expires or the programmed quantity is reached,
the CNC PILOT sets the diagnostic bit 1. This causes an error message
to be issued the next time the tool is called. If no replacement tool is
available, the program will be stopped.
 For Teach-in programs, the simple tool life monitoring is available.
Here the CNC PILOT informs you when a tool is worn out.
 In smart.Turn and DIN PLUS programs, you have the choice
between the simple tool life monitoring and the tool life
monitoring with replacement tools option. If you use
replacement tools, the CNC PILOT automatically inserts the "sister
tool" as soon as the tool is worn-out. The CNC PILOT does not stop
the program run until the last tool of the tool sequence of exchange
is worn out.
You activate/deactivate the tool life management in the parameter
"System/General settings for automatic operation/user parameter tool
life."
The CNC PILOT manages the type of monitoring, the "tool life/
remaining tool life" and the "maximum number of pieces/remaining
number of pieces" in the diagnostic bits of the tool data. You can edit
and display the diagnostic bits and the tool life in the tool editor (see
“Editing tool-life data” auf Seite 509).
You can define replacement tools when setting up the turret in
smart.Turn. The "interchange chain" can contain more than one
replacement tool. The interchange chain is part of the NC program
(see chapter titled "Tool Programming" in the "smart.Turn and DIN
Programming" User's Manual).
You must update the data on tool life and number of
pieces in the "tool management" mode when you replace
the insert of a tool.
