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)
