STEP Tools has added a feature for querying the coordinates of faces in 
each setup. Boeing was able to use this feature during its test 
machining over the weekend but questioned why the coordinates had to 
change for every setup. NIST had similar questions. Fred Proctor 
volunteered to investigate the setup issue in more detail and present 
the results at the NIST meeting.

The latest version of Boxy contains lots of different speeds and feeds 
because of the different versions of the toolpaths created during 
testing. Bengt volunteered to use the feed speed editor of the STEP-NC 
Explorer to harmonize and reduce the number of feeds and to report back 
on any difficulties.

Boeing is ready to begin test machine Boxy in steel. In order to 
complete the test we will need cross section data for the new toolpaths. 
Sandvik volunteered to update its Vericut project with the new paths so 
that the cross sections can be generated.

We discussed the meeting agenda. A new session to review the history of 
STEP-NC testing was added to the end of the first day. A new session to 
discuss a follow on-demonstration featuring more machining of Boxy with 
more automation of setup changes and automatic tool selection using an 
interface to ISO 13399 was added to the third day.

Boeing and NIST will machine boxy again this weekend and give feedback 
on the next conference call.

The next call will be at the regular times on *Wednesday June 2*.
