Technology Update
Chamfering module passes the 2,000 units an hour mark
New functions for Scada software
brings more plant transparency
 Defined internal and external chamfering as well as facing of tubes and solid bars are possible
RSA has introduced a new high-performance
circular saw called RASACUT XS that is
designed for diameters of between 6 and
30mm and achieves high production levels
that can only be matched by bundle cutting.
The product is used in the automobile
industry, especially for engine fuel lines.
In addition to this new saw, RSA has now
brought a module for the chamfering and
facing of tubes in the same diameter range
onto the market. Hourly outputs of up to
2,400 units are possible, depending on the
range of parts. The guaranteed precision of
fixed lengths is ±0.05mm.
When used in combination with the
RASACUT XS saw, the result is a top-
performance saw centre with a high output
and high level of automation and the
company claims it permits the production of
precise fixed lengths at an attractive price.
The precise and defined edging condition
of the tube ends – for example, when forming
the ends, flattening down or bending – enable
further processing costs to be reduced.

THE Siemens Industry Automation Division
has expanded its Simatic WinCC/Downtime
Monitor and Simatic WinCC/DataMonitor
software options for the Simatic WinCC V7
Scada system.
The DowntimeMonitor can now also be
used for equipment with varying speeds. The
shiftmodelhasalsobeenenhancedtoinclude
up to three shift calendars for comparing the
use of machines and plants with different
shift models. This feature can prove useful
for analysing production fluctuations,
for example when two machines deliver
varying product qualities or quantities
when operating under otherwise identical
conditions. The DataMonitor tag selection
for the Webcenter has also been improved.
The WinCC/DowntimeMonitor and
WinCC/DataMonitor software options are
used for visualising production processes
as well as capturing, analysing and
distributing production data.
The software calculates production
figures, as well as displaying and evaluating
them, which results in increased plant
transparency and productivity. In the latest
WinCC/DataMonitor version, the user
now utilises the server to distribute the
reports previously created offline in Excel.
Thanks to new tools for the installation-free
Webcenter, process values are displayed
with more transparency than ever before.
This version of the WinCC/
DowntimeMonitor and WinCC/DataMonitor
also provides the user with Gantt diagrams
for the machine status, which can quickly
zoom details of any selected period of
time, with a single mouse click immediately
leading back to the original time space
within the overall display.
It is also possible to set the maximally
attainable production speed (no of pieces/
time unit) for production changeovers.
The system can now automatically
adjust to alternately filling smaller and larger
containers or cutting shorter and longer
workpieces, for example.
This means that the actual values
in each case can always be properly
assigned to the relevant maximum value
and the correct figures calculated, for
example performance from the actual and
desired throughput.
