We discussed the results of the Renton and Kirkland demonstrations 
and the plans for the next demonstration at the University of Bath in 
the UK in the week of September 21-25.

Two parts have been selected for this demonstration.

The "Moldy" mold part will be used again and for this round we will 
make the machining faster and more portable:
- Improve the documentation by using the AP-203 E2  to annotate the 
rawpiece with the setup origin and the cutting tools with their 
minimum stick-out and flute lengths.
- Make the machining more portable by selecting commonly available 
metric tools.
- Make the machining more portable by using a "Leon Lite" algorithm 
to calculate new feed speeds using the chip load in the STEP-NC data 
and the spindle speed of the target machine.
- Make the machining faster by reducing the step-over.

The Tool selections for the new Moldy are on the ftp site. Please 
contact us immediately if any of these tooling selections will cause 
you problems.

The "Boxy" gear box part requires multiple set-ups and will be 
machined for the first time in this round.
- Test machining using STEP-NC set up data
- Test use of tolerances for different stages of the machining
- Test the STEP-NC drilling/tapping/boring operations

A first cut at the Boxy data has been made by KTH and put on the ftp site.

The new plan has been put onto the ftp site. The list of targeted new 
participants (see last slide) is not exhaustive and we invite others 
to participate. Read-only software will be made available at no cost 
on the STEP Tools web site so that new participants can view the data 
and generated codes for their machines.

A recording of the meeting is also on the site.

The next conference call will be at the regular times on Wednesday June 17

Action items
------------------
1.   Bengt and David O. to develop a "Leon Lite" algorithm to 
approximate feed speeds for machines with different spindle powers.
2.   Bengt to invite SC29/WG34 (cutting tools) to participate in the 
demonstration.
3.   David O. to develop a new AP-238 data set for Moldy that 
incorporates the lessons learned.
4.   Magnus to document the set-up's for the Moldy part as AP-203 models.
5.   David L. to create a read-only version of the STEP-NC explorer 
for machining the Moldy part.
