T24 STEP-Manufacturing
March 10 – March 12, 2008
Sandviken, Sweden

Meeting Results
·         Successful demonstration of optimized 
machining of part by Boeing using a significantly 
different machine than planned for in the original data.
·         Successful demonstration of high speed machining by U. Bordeaux.
·         Successful demonstration of closed loop 
machining using AP-203 e2 tolerances by KTH and Scania.
·         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.
·         Web site showing meeting results at: 
<http://www.steptools.com/library/stepnc/2008_sweden/index.html>http://www.steptools.com/library/stepnc/2008_sweden/index.html


ACTION ITEMS
Develop Corrigendum for AP-238 containing the following two corrections
·         Via points to enable polyline arc’s and 
helix’s because of data size discovery
·         Cross Section Area because current 
model of overcut and depth in AP-238 is insufficient for optimization

Encourage the rapid development of a machine tool model
·         Contact the Convenor of Wg7 SC1 to 
express the strong interest of T24 in this model
·         Publish model developed by University 
of Bath on the T24 web site and encourage SC1 to 
adopt the best features of this model
·         Develop implementation prototypes using 
the University of Bath model for the next meeting


GOALS FOR NEXT MEETING
The next meeting will be held September 30- 
October 2 2008 at the Connecticut Center for 
Advanced Technologies (CCAT) in Hartford, Connecticut.

The meeting will be divided into three parts – a 
Dry run day, an Industry day, and a Committee meeting day.


MEETING PREPARATION SCHEDULE
Blade model with part program in April (Brian/Pratt or Bengt/Sandvik)
First STEP-NC model in May (Martin/STEP)
Cutting tool models in May (Bengt/Sandvik)
Material selection in May (Brian/CCAT)
Machine selection in May (Brian/CCAT choices are 
DMG or UTRC Okuma or Pratt machine)
Third Wave/Deform distortion predictions in May
Prototype API for aerospace closed loop machining in May (Chen Han/Siemens)
Optimized STEP-NC machining model in June (Leon/Boeing)
STEP-NC Inspection model in July (Mike/NIST)
Closed loop machining in August (Mike/NIST, Sid/Boeing (3 axis), Brian/Pratt?)


NEW FEATURES FOR CCAT MEETING DEMONSTRATON
5-axis feed speed optimization
Machining of non- Aluminium part
Five axis closed loop machining
New cutting tools



CONTINUING FEATURES FROM SANDVIK MEETING DEMONSTRATION
Portability (machine before meeting on many machines at many sites)
Feed/speed optimization (prediction of between 10% and 30% with average of 15%)
Closed loop machining using AP-203 Edition 2 tolerances



THANKS
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.
