There was a discussion about the inspection process to be shown at 
Dallas. The HiPP team had several concerns about the precision of the 
measurements for the b-spline surface and angular corner. Two options 
were discussed as shown in FishHeadToleranceSuggestions.ppt on the 
ftp site. ftp://www.steptools.com/private/Dallas

The first option (first slide) is to follow the original plan with 
some enhancements to the procedure. The problem with this option is 
that even after the enhancements it will be difficult to make the 
measurements precisely using the procedures currently available in STEP-NC.

The second option (second slide) is to change the plan so that only 
analytical features are measured. The advantage of this option is 
that the procedures for evaluating these features can be described 
precisely and therefore they can be reproduced accurately at all of 
the machining sites.

In Japan, the measurement was done at the end of the demonstration 
and in a hurry so there were several discrepancies. Everyone wanted 
to make the measurements more precise for Dallas. The HiPP team 
commented that this was not possible for Option 1 without the 
additions being proposed for Version 2 of AP-238 by the HiPP team. 
The machining team commented that making simpler measurements for 
Dallas is OK if the measurements are done using a procedure that is 
recognized as valid by the metrology community.

It was agreed that the Option 2 measurements will be made in the 
Dallas demonstration and that Curtis Brown will provide a precise 
description for how the measurements should be made and John Horst 
will contact Len Slovensky to get a new AP-203 e2 (disguised AP-224) 
file with the tolerance data.

There was a discussion on tool path development for this 
demonstration. New tool paths are going to be developed by NIST, 
Sandvik, the University of New Zealand and Boeing. Airbus developed 
tool paths for the last demonstration. STEP Tools will assemble all 
the tool paths into a STEP-NC file containing multiple alternate 
workplans each suited to a different set of machining conditions.

David Odendahl suggested using Vought as an alternate location for 
the machining demonstration if Moriseiki cannot participate.

Alain Brail and John Horst will contact Renishaw to see if they can 
assist with the measurement portion of the demonstration.

Bengt Olsson has been able to obtain an AP-203 model for the result 
of the roughing. Many thanks to UGS Siemens and Imageware for their 
assistance. The file has been posted to the ftp site as UG_Cam_IPW.stp.
