There was a brief demonstration of using an STRL to store the current
location in a STEP-NC file. A file was saved with an STRL describing
the current workplan, workingstep and tool path location. The file was
then opened again in a new version of the STEP-NC Explorer and the STRL
was used to select the workplan, workingstep and tool path to show to
the user.<br>
<br>
We discussed three possible scenarios for the demonstrations to be
given at NIST in June. A cutting tool scenario was presented by
Sandvik. In this scenario a cutting tool database contains information
about tool actual dimensions and remaining tool life. A system that
wants to the machine the Boxy part goes to the cutting tool database to
get information about each tool in the program by selecting the STRL's
for the tools. In the Boxy file there are multiple alternate toolpaths
for several of the machined features. With the information sent back
from the cutting tool database, a system selects the best cutting tools
and tool paths to machine the Boxy part at the current time. For more
information on this scenario see the URL below.<br>

<br>
In the second scenario a feature is added to the Moldy part and and a
request to plan tool paths for the feature is sent to a remote site as
an STRL. The remote site generates tool paths and sends the result back
as another STRL. The home site then simulates the new program with the
new feature and after verification the part is machined. For the
demonstration, the main Moldy program may be stored as an STRL at
Boeing. The amended Moldy program with the new feature will be stored
at NIST and the system to create tool paths for machining the new
feature will be at the University of Bath.<br>
<br>
In the third scenario energy consumption estimates are made by sending
the STRL for a STEP-NC program to several different sites. Each site
uses local software to estimate the energy necessary to make the part
on their machines and the results are compiled so that a contractor can
determine the best solution.<a class="moz-txt-link-freetext"

The next conference call will be held at the usual times in three
weeks, one week longer than usual because of Thanksgiving.<br>
