David Loffredo deputized for Martin Hardwick on this call.

A brief demonstration of the status of the frame definition and fixture 
handling in the STEP-NC Explorer was shown.   The measurement geometry 
for frame definition and compensation workingsteps are now being 
properly aligned. The fixture is now mounted correctly on the machine, 
but the workpiece is not yet being transformed into the proper place in 
relation to the fixture.   These remaining issues will be worked out in 
time to make an updated STEP-NC Explorer available for the next phase of 
testing.

Updates to the closed loop model were reviewed.   No comments, but David 
Odendahl will do more detailed review and get back to us.

Reviewed data set with Setup 1 with 5 datums machined provided by 
Magnus.   The data set has the new in process-models, but does not yet 
have any datums defined on them.  The model also has many of the 
outdated workpieces still in it.   Discussed some of the recent and 
planned changes to STEP-NC Machine to make it easier to manage the 
workpieces.

No progress has been made on changing the feeds and speeds from steel to 
aluminum because Boeing Fred has been out sick and there have been 
airplane issues to deal with.

The new okuma machine tool model has been delayed because the STL 
translator that David O was using had problems with the spindle 
geometry.   He is looking for different translation software and Sid is 
looking for a better model.
