TENS POINT (infeed)
• 0=Perpendicular with G0
• 1=Perpendicular with G1
• 3=Oscillation with G1
If another value is programmed for the parameter
VARI, the cycle aborts after output of the alarm
61102 "Operating mode not defined correctly".
Cutter diameter=slot width (WID)
• With complete machining, finishing machining
only takes place on the base.
• In machining mode VARI=32 positioning is
paraxial in Z with G1 followed by finish-cutting
(infeed possible via MIDF).
_FALD (final machining allowance on slot base)
A separate final machining allowance on the base is
taken into account in roughing operations.
_STA2 (insertion angle)
Parameter _STA2 defines the maximum insertion
angle for the oscillation motion.
• Vertical insertion (VARI=0X, VARI=1X)
Vertical depth insertion is always performed at the
same position on the machining plane down to the
final depth of the slot.
• Insertion with oscillation on the center axis of
the slot (VARI=3X)
means that the mill center point oscillates along an
oblique linear path until it has reached the next
current depth. The maximum insertion angle is
programmed under _STA2, the length of the
oscillation path is calculated from LENG-WID.
The oscillating depth infeed ends at the same point
as with vertical depth infeed motions, the starting
point in the plane is calculated accordingly. The
roughing operation begins in the plane once the
current depth is reached. The feedrate is
programmed under _FFD.
