A brief demonstration of frame definition in the STEP-NC Explorer
was shown. The next step is to enable movement of the workpiece in
the fixture in response to measurements. An information model has
been developed for 'fixture_usage' that allow both the origin of the
fixture relative to the machine, and the origin of the setup
relative to the fixture to be set. The model is being implemented in
the STEP-NC Explorer and should be demonstrated next week. A
suggestion was made that it should be possible to set the location
of the fixture using the FARO arm. This will be further discussed at
the Renton meeting.<br>
<br>
The following schedule for completing the demonstration was
discussed:<br>
<br>
Week of September 15th Frame definition operational
(current)<br>
Week of September 22nd Workpieces that can move in the
fixture - decide what needs to be measured for each setup -
recommendations for feeds and speeds<br>
Week of September 29th Setup compensation - new STEP-NC with
necessary faces machined in first setup - correct feeds and speeds
in the AP-238<br>
Week of October 6th Testing at Boeing<br>
Week of October 13th Demo<br>
<br>
There is an issue in the second setup because one of the three faces
machined in the first setup is at the bottom of the part where it
cannot be measured. KTH will be asked to produce a new version of
Boxy that machines 5 faces (the top and part of the four sides) in
the first setup.<br>
<br>
The part will be machined in aluminum. At NIST it was machined in
steel so Boeing will compute new speeds and feeds.<br>
<br>
The next call will be at the regular times on Wednesday September
22. A meeting recording of this call is at the ftp below.<br>
