4. Rapid movement (G0) up to the approach plane.
5. Roughing operation.
It is carried out in layers, until reaching the total depth minus the
finishing stock at the bottom "
δ
z".
5.1. Penetration "I" at feedrate "Fz" at an angle "
β
".
5.2. 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.
It is carried out following paths concentric to the profile, in
the same direction as the outside profile was defined.
The islands are machined in the opposite direction.
5.3. Rapid withdrawal (G0) up to 1 mm off the machined surface.
6. Rapid withdrawal (G0) up to the safety plane (Zs).
7. It selects the finishing tool and it approaches in rapid (G0) down
to 1 mm from the roughed out bottom.
8. Finishing of the bottom of the pocket.
8.1. Penetration at feedrate "Fz" at an angle "
θ
".
8.2. 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.
It is carried out following paths concentric to the profile, in
the same direction as the outside profile was defined.
The islands are machined in the opposite direction.
9. Rapid withdrawal (G0) up to the approach plane.
10. Finishing of the side walls.
It is carried out in "N" passes at the finishing feedrate "F" and
with tangential entry and exit.
The outside profile in the same direction that was defined and
the islands in the opposite direction.
11. Rapid withdrawal (G0) up to the safety plane (Zs).
