Stock - Rough Reworking

The Stock rework roughing allows to resume the part with a stock management. GO2cam searches for the material remaining at the time of the application of the roughing cycle by comparing the polyhedron covering the solid or the surfaces, and the polyhedron resulting from the preceding machining phases.

Key Points

GO2cam offers 4 calculation modes for the stock:
Last: comparison with the last progressive "grey" stock calculated
Cycle: comparison with the exact envelope (polyhedron) resulting from the preceding machining phases. The method is more accurate than with the “Last” stock calculation. However, the computation times are longer.
Auto: a mix of the 2 methods. The polyhedron is calculated only for the phases whose stock calculation has not been selected.
Finishing: this method of calculation is to be used in cases where the machined material is very hard. It allows to create false material in the corners compared to the reference tool. Which will generate trajectories with air machining, but which avoids certain collisions. Machining time will be increased. A Diameter and a Tool reference radius must be entered.
