4.16.2 Basic operation.<br />
The CNC calculates the initial coordinate depending on the geometry of the pocket and the<br />
tool radius.<br />
1 It selects the roughing tool and starts the spindle in the requested direction.<br />
2 Rapid movement (G0) to the roughing starting point and the safety plane (Zs). Depending<br />
on the starting plane, it first moves in XY and then in Z or vice versa.<br />
3 Rapid movement (G0) up to the approach plane.<br />
4 Roughing operation. It is carried out in layers until the total depth is reached.<br />
First, penetration "I1" at feedrate "Fz" at an angle "β". Then, milling of the pocket surface<br />
up to a distance "δ" from the pocket wall. It is carried out at feedrate "F" and, if necessary,<br />
it recalculates the pass (Δ) so all the passes are identical.<br />
The pocket is machined following paths concentric to the profile, in the same direction<br />
as the outside profile was defined. The islands are machined in the opposite direction.<br />
And last, rapid withdrawal (G0) up to 1 mm off the machined surface.<br />
5 Rapid withdrawal (G0) up to the approach plane.<br />
6 It selects the pre-finishing tool and starts the spindle in the requested direction.<br />
7 Pre-finishing operation for the side walls. It is carried out in layers until the total depth<br />
is reached. The cycle will not run the pre-finishing passes that coincide with any previous<br />
roughing pass.<br />
It is carried out with the pass indicated by "I2" and at the pre-finishing feedrate "F". The<br />
outside profile in the same direction that was defined and the islands in the opposite<br />
direction.<br />
8 Rapid withdrawal (G0) up to the approach plane.<br />
9 It selects the finishing tool and starts the spindle in the requested direction.<br />
10 Finishing of the side walls. It is carried out with the pass "ε" and direction indicated by<br />
the icon.<br />
Rapid withdrawal (G0) up to the safety plane (Zs).<br />
