Local stock

This option allows to define for an operation a local stock different from the part one.

In this case the machining area and the altitudes are not calculated with the part original stock but with this local stock.

Option to use in a roughing where we do not want to machine all the part BUT mostly take into acount a stock which is not a cube (essentially for Z rapids).

 

In both examples below the yellow stock represents the original stock and the green stock the local stock for an operation.

 

2D Machining

End miling with original stock

End miling with local stock

3D Machining

In the example below the roughing has been calculated on the green local stock.

Original stock

Local stock for the roughing

Result

The tool paths are calculated with the green stock.

The rapid tool paths are calculated with the green stock.

TURNING

In the example below the roughing has been calculated with the initial stock in yellow (on the left) and on the green local stock on the right)

 

 

 

If the operation asks to update the stock it is the part original stock which will be updated.In the last example we will have a stupid result as the rapid movements does not update the stock.
