Mastercam, Siemens, Delcam, EdgeCAM and OpenMind have confirmed 
participation at the IMTS meeting. Others are reviewing - with no 
negative responses yet.

The following was proposed as the IMTS meeting agenda:

1. Quick summary of what is on the poster
2. Show them our example - discuss the timeline
3. Listen to their concerns
4. Action items and follow-up

We discussed the scope for the first round of data exchange. Three 
possibilities were suggested:

a. CAM to CNC exchange using CC1 (toolpaths).
b. CAM to CAM exchange using CC3 (operations)
c. If there is sufficient time and interest a combination of a and b.

The issue with CC1 is that it is, in many ways, an update of the current 
M&G codes to include STEP geometry. Many of the advantages of STEP-NC 
including last minute tooling changes, better simulations and adaptive 
fixturing require CC3 so we want CC3 to be implemented for CAM to CNC 
exchange as well as for CAM to CAM exchange. The following file from 
Alain Brail gives more details:

If CC3 is the focus then it was suggested that we should restrict the 
domain to 3-axis machining and use Boxy as the test part. This has the 
advantage of allowing full participation by all the vendors, and giving 
the end users the data necessary for advanced applications. The 
following timeline was suggested for testing this 3-axis data exchange:

Timeline
1. Go/No-go for each participant in 1-3 months.
2. First meeting in 3-6 months - make the Boxy part in your systems so 
we can review.
3. Second meeting at 9-12 months write a Boxy STEP file from your systems.
4. Third meeting at 15-18 months read our Boxy data into your system 
http://www.steptools.com/products/stepncmachine/samples/boxy/
5. Fourth meeting 21-24 months test data exchange of Boxy's between all 
participants.

This timeline to be adjusted for the concerns of the vendors and end 
users at the IMTS meeting.

The next telecon will be held on Wednesday August 22nd at the regular 
times, but one week earlier than usual so that we can make plans to 
contact any vendors who have not yet responded to the e-mail. A 
recording of this meeting is at the following ftp site:

Martin Hardwick
Team Leader STEP-Manufacturing

Action Item
1. STEP Tools to measure the file size for Boxy in Part 21 and Part 28 
forms.
2. All to review the proposed scope and timeline.
