The dates of the demonstration has been moved back to May 14 and 15 
so that the T24 technical meetings can take place in the following 
week at the SC4 meeting in Vancouver. The tentative plan is for 
machining demonstrations to be given at a Boeing facility in Seattle, 
and for inspection demonstrations using a scanning probe to be given 
at a Mitutoyo facility in Seattle.

There was a discussion of which part should be used for the 
demonstration. The two favorites were the following:

ftp://ftp.steptools.com/private/Vancouver/Sandvik_test_parts/Sandvik%20Demo%206.pdf

The first part has the advantage of allowing us to test data from a 
new data source (Mastercam). The second part has the advantage of 
being faster to machine.

The University of Bath Machine Tool model has been substantially 
updated since it was presented to T24 in April. The latest version 
can model machine tool limits and parallel kinematics.

The technical goal for the demonstration is to show data exchange of 
machining processes between enterprises. A document describing these 
goals and the scenario for the demonstration has been made by Fred 
Proctor. A diagram showing the scenario has been made by Xun Xu.

The next conference call will be on Wednesday November 12. The goal 
for the call will be to make the final part selection.

Action items
------------------
Gary Hargreaves to find out the material and approximate machining 
time for the Mastercam part.
Bengt Olsson to find out the material for the Sandvik part.
Martin Hardwick to make STEP-NC data for the candidate parts.
