We discussed the machining and measurement demonstration to be held at 
the Future of Flight Museum in Mukilteo, Washington State on October 
5th. We are planning for this to be a joint meeting of ISO STEP, 
MTConnect and OMAC. The demonstration will be given for this audience 
and a team of Boeing managers from the nearby plants.

We discussed what units we should use for the part and tentatively 
agreed that they should be millimeters including the tool paths, the 
GD&T and the cutters.

We discussed what material and agreed that it should be a hard metal 
such as titanium and that the machine can hold tolerances to about 0.2 
of a thousandth inch (.0002") or 12.5 micrometers for this material.

We discussed if we should machine a part of more relevance to the 
aerospace industry and whether we should obtain the machining data from 
an aerospace CAM system such as CATIA or NX.

We discussed whether we should have a technical face to face meeting in 
the Spring.

Many apologies for a failure to make a recording of this conference 
call. The next meeting will be at the regular times on January 27th.
