<u>Meeting Results<br>
</u>· <b>Successful
demonstration of optimized machining of part by Boeing using a
significantly different machine than planned for in the original
data.<br>
</b>· <b>Successful
demonstration of high speed machining by U. Bordeaux.<br>
</b>· <b>Successful
demonstration of closed loop machining using AP-203 e2 tolerances by KTH
and Scania.<br>
</b>· <b>Successful
integration by Sandvik and STEP Tools of ISO 13399 tool data and AP-238
machining data to enable the usage of actual cutting tool data at the
beginning of machining and recording of changes to cutting tool data at
end of machining.<br>

<br>
<u>ACTION ITEMS<br>
</u>Develop Corrigendum for AP-238 containing the following two
corrections<br>
</b>· <b>Via points to
enable polyline arc’s and helix’s because of data size discovery<br>
</b>· <b>Cross Section
Area because current model of overcut and depth in AP-238 is insufficient
for optimization<br>
<br>
Encourage the rapid development of a machine tool model<br>
</b>· <b>Contact the
Convenor of Wg7 SC1 to express the strong interest of T24 in this
model<br>
</b>· <b>Publish model
developed by University of Bath on the T24 web site and encourage SC1 to
adopt the best features of this model<br>
</b>· <b>Develop
implementation prototypes using the University of Bath model for the next
meeting<br>
<br>
<br>
<u>GOALS FOR NEXT MEETING<br>
</u>The next meeting will be held September 30- October 2 2008 at the
Connecticut Center for Advanced Technologies (CCAT) in Hartford,
Connecticut.<br>
<br>
The meeting will be divided into three parts – a Dry run day, an Industry
day, and a Committee meeting day.<br>
<br>
<br>

Machine selection in May (Brian/CCAT choices are DMG or UTRC Okuma or
Pratt machine)<br>
Third Wave/Deform distortion predictions in May<br>
Prototype API for aerospace closed loop machining in May (Chen
Han/Siemens)<br>
Optimized STEP-NC machining model in June (Leon/Boeing)<br>
STEP-NC Inspection model in July (Mike/NIST)<br>

Brian/Pratt?)<br>
<br>
<br>
<u>NEW FEATURES FOR CCAT MEETING DEMONSTRATON<br>
</u>5-axis feed speed optimization<br>
Machining of non- Aluminium part<br>
Five axis closed loop machining<br>
New cutting tools<br>
<br>
<br>
<br>
<u>CONTINUING FEATURES FROM SANDVIK MEETING DEMONSTRATION<br>

sites)<br>
Feed/speed optimization (prediction of between 10% and 30% with average
of 15%)<br>
Closed loop machining using AP-203 Edition 2 tolerances<br>
<br>
<br>
<br>
<u>THANKS<br>
</u>T24 would like to thank Sandvik, Scania, KTH and EuroSTEP and all our
hosts in Sweden for their wonderful hospitality, for letting us use their
excellent facilities and for enabling a very productive meeting.<br>
