Further notes
You must activate a double-edged tool before calling
the grooving cycle. You must enter the offset values for
the two tool edges in two successive D numbers of the
tool, the first of which must be activated before the cycle
is called. The cycle determines itself which of the two
tool offsets it requires for which machining step and
activates them automatically. After the cycle is
completed, the offset number programmed before the
cycle call becomes active again. If no D number has
been programmed for a tool offset when the cycle is
called, the cycle is aborted with alarm
61000 "No tool offset active"
and the cycle is aborted.
For SW 5.1 and higher, cycle setting data _ZSD[4]
can be used to influence the retraction after the 1st
groove.
_ZSD[4]=0 means retraction with G1 as before,
_ZSD[4]=1 means retraction with G0.
With SW 6.2 and higher, cycle data _ZSD[6] can be set
to define how the tool offset is handled in the cycle.
_ZSD[6]=0 TO is exchanged internally in the cycle
(without orientatable toolholder)
_ZSD[6]=1 TO is not exchanged internally in the cycle
(with orientatable toolholder)
