5.5 Tool management ShopTurn
Tools that are in use for long periods are subject to wear. You can
measure this wear and enter it in the tool wear list. ShopTurn then
takes this information into account when calculating the tool length or
radius compensation. This ensures a consistent accuracy in
workpiece machining.
Operating sequence
Select "Tool wear" via softkey
Place the cursor on the tool whose wear data you want to enter.
Enter the differences for length (∆Length X, ∆Length Z) and
radius/diameter (∆Radius/∆∅) in the appropriate columns.
The wear data entered is added to the radius but subtracted from the
tool length. A positive differential value for the radius therefore
corresponds to an oversize (e.g. for subsequent grinding).
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.
The tool monitoring functions are activated via display machine data.
Please follow the machine manufacturer's instructions!
Operating sequence
Select "Tool wear" via softkey
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
Tool life is monitored on the basis of the selected tool cutting edge.
