2.13.8 Entering tool wear data
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. ShopMill then
takes this information into account when calculating the tool length or
radius compensation. This ensures a consistent accuracy in
workpiece machining.
When you enter the wear data, ShopMill checks that the values do not
exceed an incremental or absolute upper limit. The incremental upper
limit indicates the maximum difference between the previous and new
wear value. The absolute upper limit indicates the maximum total
value that you can enter.
The upper limits are set in a machine data code.
Please refer to the machine manufacturer's instructions.
îš¾ Select the "Tool wear" softkey in the "Tools WOs" operating area.
Example of a tool wear list with variable location allocation
îš¾ 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.
