ShopTurn allows you to monitor the tool life of the tools automatically
to ensure constant machining quality.
You can also disable tools that you no longer want to use or identify
them as oversize.
Tool monitoring can be activated via a machine data code.
Please also refer to the machine manufacturer's instructions.
With the tool life T (Time), the service life for a tool with machining
feedrate is monitored in minutes. When the remaining tool life is = 0,
the tool is set to "disabled". The tool is not put into operation on the
next tool change. If a replacement tool is available, it is inserted in its
place.
Tool life is monitored on the basis of the selected tool cutting edge.
With the count C, the number of workpieces machined by the tool is
counted. The tool is also disabled in this case, when the remainder
reaches "0".
With wear W, the greatest value in the wear parameters . Length X,
. Length Z, or . Radius or . ¬ in the wear list is monitored. Here, too,
the tool is disabled if one of the wear parameters reaches the value for
wear W.
The wear monitoring function must be set up by the machine
manufacturer.
Please also refer to the machine manufacturer's instructions.
The pre-warning limit specifies a tool life, workpiece count or wear at
which the first warning is displayed.
The value for output of a warning due to the wear stage reached is
calculated from the difference between the maximum wear and the
warning limit entered.
Individual tools can also be disabled manually if you no longer want to
use them for workpiece machining.
In the case of oversize tools, neighboring magazine locations (left and
right adjacent location) are only reserved alternately, i.e. you can only
insert the next tool in the next magazine location but one. (This can
also contain an oversize tool.)
