4.15.2 Basic operation.
Canned cycles (·M· model)
The CNC calculates the initial coordinate depending on the geometry of the pocket and the
tool radius.
1 Drilling operation. Only if it has been programmed.
2 It selects the roughing tool and starts the spindle in the requested direction.
3 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.
4 Rapid movement (G0) up to the approach plane.
5 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.
The pocket is machined following paths concentric to the profile, in the same direction
as the outside profile was defined. The islands are machined in the opposite direction.
And last, rapid withdrawal (G0) up to 1 mm off the machined surface.
6 Rapid withdrawal (G0) up to the safety plane (Zs).
7 It selects the finishing tool and it approaches in rapid (G0) down to 1 mm from the
roughed-out bottom.
8 Finishing of the bottom of the pocket.
First, penetration at feedrate "Fz" at an angle "θ". Then, milling of the bottom of the pocket
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.
The pocket is machined following paths concentric to the profile, in the same direction
as the outside profile was defined. The islands are machined in the opposite direction.
9 Rapid withdrawal (G0) up to the approach plane.
10 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. The cycle executes the outside
profile in the same direction that was defined and the islands in the opposite direction.
11 Rapid withdrawal (G0) up to the safety plane (Zs).
