Turning Cycles
4.2 Preconditions
Machining status messages
Status messages are displayed on the control monitor
during processing of the turning cycles. The following
messages can be displayed:
• "Thread start <No.> – longitudinal thread machining"
• "Thread start <No.> – face thread machining"
In each case <No.> stands for the number of the figure
that is currently being machined.
These messages do not interrupt program processing
and continue to be displayed until the next message is
displayed or the cycle is completed.
Cycle setting data
For the stock removal cycle CYCLE95, Software
Release 4 and higher has provision for setting data that
is stored in module GUD7.DEF.
Cycle setting data _ZSD[0] can be used to vary the
calculation of the depth infeed MID in CYCLE95. If it is
set to zero, the parameter is calculated as before.
• _ZSD[0]=1 MID is a radius value
• _ZSD[0]=2 MID is a diameter value
For the groove cycle CYCLE93, software release 4 and
higher has provision for setting data in module
GUD7.DEF. This cycle setting data _ZSD[4] can affect
the retraction after the 1st groove.
• _ZSD[4[=1 Retraction with G0
• _ZSD[4]=0 Retraction with G1 (as before)
With SW 6.2 and higher, there is an option for
setting mirroring behavior in _ZSD[6] for grooving
cycle CYCLE93.
•
_ZSD[6]=0 The tool offsets are exchanged in the
(for use without orientatable toolholder)
•
_ZSD[6]=1 The tool offsets are not exchanged in
(for use with orientatable toolholder)
