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 />
