Tool life monitoring
If desired, you can have the MANUALplus 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 MANUALplus generates an error message and stops program
execution after the end of the program. If you are working with
program repeats (M99 in DIN programs), the system is stopped after
execution of the current repeat.
 For Teach-in programs, the simple tool life monitoring is available.
Here MANUALplus 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 or the tool life
monitoring with replacement tools option. If you use
replacement tools, the MANUALplus automatically inserts the
"sister tool" as soon as the tool is worn-out. The MANUALplus 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 type of monitoring data, the "tool life/remaining tool life" or the
"maximum number of pieces/remaining number of pieces" are
managed in the tool data. They are also edited and displayed in the tool
data (see "Editing tool-life data" on page 483).
You can define replacement tools when setting up the turret. 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.
