Tool life monitoring
If desired, you can have the control 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 control 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, simple tool life monitoring is available
Here, the control informs you when a tool is worn out.
With smart.Turn and DIN PLUS programs, you can choose
between the simple tool life monitoring feature or the tool life
monitoring with replacement tool option.
If you use replacement tools, the control automatically inserts
the sister tool as soon as the tool is worn out. The control does
not stop the program run until the last tool of the tool sequence
of exchange is worn out.
You can activate / deactivate the tool life management in the
lifeTime (601801) user parameter.
The control 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
Tool editor
mode of
operation.
Further information: "Editing tool life data", Page 569
If a tool is renewed (e.g. replacement of indexable
inserts), the tool life and the quantity must be reset in
Tool editor
mode of operation.
You can define replacement tools when setting up the tool carrier
in
smart.Turn
mode of operation. The sequence of exchange can
contain more than one sister tool. The sequence of exchange is a
part of the NC program.
