3. Rapid movement (G0) up to the approach plane.
4. Roughing operation.
It is carried out in layers, until reaching the total depth minus the
finishing stock at the bottom "
δ
z".
4.1. Penetration "I" at feedrate "Fz" at an angle "
β
".
4.2. Milling of the pocket surface up to a distance "
δ
" from the
pocket wall. It is carried out at feedrate "F" and, if necessary,
it recalculates the pass (
∆
) so all the passes are identical.
4.3. Rapid withdrawal (G0) to the center of the pocket, 1 mm off
the machined surface.
5. Rapid withdrawal (G0) up to the safety plane (Zs).
6. It selects the finishing tool and it approaches in rapid (G0) down
to 1 mm from the roughed out bottom.
7. Finishing of the bottom of the pocket.
7.1. Penetration at feedrate "Fz" at an angle "
θ
".
7.2. Milling of the bottom of the pocket up to a distance "
δ
" from
the pocket wall. It is carried out at finishing feedrate "F" and,
if necessary, it recalculates the finishing pass (
∆
) so all the
passes are identical.
8. Withdrawal, in rapid (G0), to the center of the pocket in the
approach plane (1 mm off the "Z" surface).
9. Finishing of the side walls.
It is carried out in "N" passes at the finishing feedrate "F" and with
tangential entry and exit.
10. Rapid withdrawal (G0) to the center of the pocket in the safety
plane (Zs).
If it has a multiple machining operation associated with it, it executes
the following steps as often as necessary:
11. Rapid movement (G0) to the next point.
12. Repeats steps 3, 4, 5, 6, 7, 8, 9, 10.
