9.13.1 Basic operation
1. If the spindle was previously running, it maintains the turning direction. If it was not in movement,
it will start by turning clockwise (M03).
2. Rapid movement (G0) of the longitudinal axis from the starting plane to the reference plane.
3. First penetrating operation. Movement of longitudinal axis at the feedrate indicated by "V" to the
incremental depth programmed in "B+D".
4. Milling of the pocket surface at work feedrate in the passes defined by "C" up to a distance "L"
(finishing pass) from the pocket wall.
5. Finishing pass milling, "L" at the work feedrate defined by "H".
6. Once the finishing pass has been completed, the tool withdraws at the rapid feedrate (G00) to
the center of the pocket, the longitudinal axis being separated 1 mm (0.040 inch) from the
machined surface.
7. New milling surfaces until reaching the total depth of the pocket.
·1· Movement of the longitudinal axis at the feedrate indicated by "V", up to a distance "B" from
the previous surface.
·2· Milling of the new surface following the steps indicated in points 4, 5 and 6.
8. Withdrawal at rapid feedrate (G00) of the longitudinal axis to the initial or reference plane,
depending on whether G98 or G99 has been programmed.
