Using Transfer Line Cycles
Chapter 31
31-25
Once you enter information in the QuickView screens, the cycle acts just
like a part program. The program runs within these conditions:
G90 -- all the cycles operate in absolute mode. If you enter try to a G91
into the QuickView prompt you’ll get an error message.
WARNING: If you enter a G91 into a transfer line part
program, the control will run in incremental mode, even though
the program was designed for absolute mode. Using G91 in any
of the transfer line part programs may result in unpredictable
axis motion.
G98/99 -- all the cycles return to the R plane just as if a G99 was
programmed. If you try to program a G98, it has no effect on the cycle.
Plane Select, G17, G18, G19 -- these G-codes have no effect on the
system. Since all of the cycles in the transfer line option use only two
axes, plane select doesn’t apply. In all of the cycles:
- the first axis is the drilling axis. Its default name is X.
- the second axis is the positioning axis. Its default name is Y.
- if you select only one axis, it will be the drilling axis.
Using Spindles with the Cycles
If the system is using the default AMP and PAL, spindle command is sent
from PAL to the PLC, and the PLC controls the spindle. Your system
installer may have modified the system’s PAL and AMP if you are using a
solid tapping cycle, or if the configuration requires the spindle to be
controlled by the CNC.
This section defines the QuickView prompts for all the templates, and
shows the QuickView graphic for each cycle.
All of the templates include required fields that need to be completed for
the control to create the cycle. Some cycles includes optional fields for
features such as Feed to Hard Stop, Adaptive Depth, and Adaptive Feed.
These features are mutually exclusive. If you enter data for more than one
feature, an error message appears.
