4.13.1 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 "δz".
First, penetration "I" at feedrate "Fz" at an angle "β". Then, 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 (Δ) 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 "θ". 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 (Δ) so all the passes are identical.
8 Rapid withdrawal (G0) to the center of the pocket in the approach plane.
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).
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.
