Insertion Insertion strategy:
Oscillation: Oscillating insertion with the programmed angle (EW).
Helical: Helical insertion with the programmed radius (ER) and the programmed
gradient (EP).
Center: For this insertion strategy, a milling cutter is required that cuts in the center.
It is inserted at the programmed feedrate (FZ or FX).
EW Insertion angle (for oscillation only) Degrees
EP Maximum Insertion gradient (only for helical)
The gradient of the helix may be smaller in some geometric conditions.
mm/rev
ER Insertion radius (only for helical)
The radius must not be larger than the cutter radius, otherwise material will remain.
Also make sure the pocket is not violated.
mm
FZ Depth infeed feedrate (for end face/end face C and end face Y with central insertion
only)
mm/tooth
mm/min
FX Depth infeed feedrate (for peripheral surface/peripheral surface C and peripheral
surface Y with central insertion only)
mm/tooth
mm/min
Retraction
mode
If more than one insertion point is necessary, specify the retraction height to which
the tool retracts between insertion points:
To retraction plane
Z0+safety clearance (for end face/end face C and end face Y only) or
X0+safety clearance (for peripheral surface/peripheral surface C and peripheral
surface Y only)
If there are no islands larger than Z0 (X0) in the pocket area, Z0 + safety clearance
(X0 + safety clearance) can be programmed as the retraction mode.
