3.14.1 Basic operation.
1 It selects the roughing tool and starts the spindle in the requested direction.
2 Rapid movement (G0) to the center of the pocket and the safety plane (Zs). Depending
on the starting plane, it first moves in XY and then in Z or vice versa.
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 "

z".
First, "I" penetration and approach to the pre-emptied side with tangential entry. Then,
milling of the pocket surface up to a distance "

" from the pocket wall. It is carried out
at feedrate "F" and, if necessary, it recalculates the pass (

) so all the passes are identical.
And last, 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.
Penetration at feedrate "Fz" at an angle "

". Milling of the bottom of the pocket up to a
distance "

" 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. The finishing operation 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).
