We discussed the setup issue. The operator would like for the workpiece 
origin to be the same for each setup. The origin can be set in the 
STEP-NC Explorer by right clicking the workplan that defines the setup 
and picking the "Edit Placement" option. In the current version of Boxy 
the setup is defined so that the origin is in the middle of the top 
face. NIST will try defining the origin to be the bottom, back, left 
corner of the rawpiece so that it can be the same for each setup. 
Adjustments will have to be made when material has already been removed 
for a face used in the setup.

Boeing has made new cross section data for Boxy using Vericut and STEP 
Tools has added the cross sections to the latest version on the ftp site:

We discussed STEP URL's. Other groups are interested in putting STEP 
data onto the Internet. STEP-NC is different because in addition to 
defining a data exchange standard it defines an environment for 
machining a part. This environment needs to be able to evolve as more 
detail is added to the machining program. In this cycle we have made 
significant use of STRL's to update Boxy with new Mastercam tool paths. 
In future cycles we want to start use them to implement distributed 
process planning, path planning, closed loop machining applications.

STRL's will be further discussed in the technical sessions (Thursday 
June 17 and Friday June 18) of the NIST meeting. A new agenda for that 
meeting has been put onto the ftp site.

Please note that a new session has been added to the end of Wednesday to 
discuss STEP-NC and Mil Standard 31000.

The next call will be at the regular times on *Wednesday June 9*.

The recording of this call has not yet been posted.
