4.18.1 Basic operation.
1 It selects the roughing tool and starts the spindle in the requested direction.
2 Rapid movement (G0) to the roughing starting point and the safety plane (Zs). Depending
on the starting plane, it first moves in XY and then in Z or vice versa.
3 Rapid approach (G0) up to 1 mm off the surface "Z".
4 Roughing operation. It is carried out in layers, until reaching the total depth minus the
finishing stock at the base "δz".
First, penetration "I" at feedrate "Fz". Then, milling of the boss surface up to a distance
"δ" from the side 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 starting
point.
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 last
roughing operation.
7 Finishing of the base of the boss.
Penetration at feedrate "Fz". Milling of the base of the boss up to a distance "δ" from the
side wall. It is carried out at the finishing feedrate "F" and with the roughing pass.
8 Rapid withdrawal (G0) to the starting point 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) up to 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.
