Stock Calculation
Cycles: PAM, Roughing/Reworking (shape), Finish Contour (shape), Stock (Rough Reworking)
Definition
GO2cam researches the remaining material while applying the toolpath, by comparing the polyhedron covering the machined solid and the polyhedron calculated from previous machining operations (mode Cycle).
To simplify the stock calculation, the comparison can be done according to the ‘grey’ stock visible on screen. In that case, we take into account only the machining operations on which the stock calculation is set to ON (mode Last).
The last option 'Finish' is not included in cycle Finish Contour (shape)
Several modes to calculate the stock
Auto | Mix of the 2 methods ‘Last’ and 'Cycle': the grey stock is taken for calculation except for the operations where stock calculation is OFF. In that case, the polyhedron is taken. |
Last | Comparison with the last evolutive stock calculated. |
Cycle | Comparison with the exact enveloppe (polyhedron) from previous machining cycles. This method is more precise, but also much longer than the method ‘Last’. |
Finish | Mode combined with Reference diameter and Reference radius. This option enables to create false material in the corners according to the reference tool. It will sometimes generate air cutting toolpaths, but which may avoid some collisions. Machining time will be increased but calculation time decreased. A Diameter and a Tool reference radius must be entered. To be used in case of hard material for instance. |
Below is an example of Stock Calculation in the Rough/Rework operation.
Auto Mode: the rework is programmed on the workpiece. | Finishing with Reference diameter=10mm and radius=5mm. There are more toolpaths generated, especially on the fillets, for a better finishing quality. |
