<p>We continued the blue sky discussion on IMTS 2018 with a focus on
how to run the demonstration. The following suggestions were made:<br>
</p>
<ol>
<li>Machine and measure in multiple stages at the booths of
multiple vendors<br>
</li>
<li>The required fixture and tooling should be known well in
advance</li>
<li>Part and feature dimensions should be varied at the last
minute, as should the routings between vendors<br>
</li>
<li>Use an autonomous robots and/or students to move the part
around the show.</li>
<li>Have screens showing a blackboard of the current results and
activities. </li>
</ol>
<p>The following questions were asked about the process:</p>
<ol>
<li>Will it be a 3-axis or 5-axis challenge?</li>
<li>Will it be a mill or mill-turn challenge?</li>
<li>Will it be an additive and subtractive challenge or an
exclusively subtractive challenge?</li>
</ol>
<p>The following observations were made about the exiting test
parts:</p>
<ol>
<li>Fishhead is heavy (25 pounds before machining, 5 pounds
after).</li>
<li>Boxy requires careful setup against the datums</li>
<li>CDS part with a cone in the middle is familiar for machinists</li>
<li>NIST has a test part for additive manufacturing see

</ol>
<p>To start the process of selection we asked what pain points are
we addressing?<br>
</p>
<ol>
<li>Interoperability / build anywhere / measure anywhere<br>
</li>
<li>Correction of features</li>
<li>Flexible process and quick support for new applications

</ol>

<p>The next conference call will be on July 19th <b>one week later
than normal</b> because of the demonstration at the DMDII on
July 12th.</p>
