We discussed the working draft of Edition 2 of AP238:
https://github.com/stepmfg/ap238e2 - Document Source
https://stepmfg.github.io/ap238e2/ - Viewable Version

The current version shows the text of edition 1 updated to use the new 
technology. The next task is to integrate the changes developed during 
the testing to create a complete working document. After that we must 
divide into modules so that extensions can be developed for the 
different units of functionality.

We discussed the IMTS 2018 grand challenge:
    http://fishhead.steptools.com:8080/

We propose to machine the part at multiple booths around the show. The 
machining will be stopped at convenient points during the roughing and 
started again on a new machine. At the end of the machining the part 
will be measured for conformance to its AP242 tolerances on a CMM. 
Measurements will be taken at the end of each machining stage using the 
digital twin.

We discussed the schedule for the Korea meeting.  The first day will 
focus on the proposal for  new federated architecture for STEP, 
MTConnect and QIF. The second day will be hands on demonstrations for 
Edition 1. The third day will be a discussion of the working draft for 
Edition 2.

The next conference call will be on Wednesday October 4th.
