We reviewed the feed speed editor. The functionality looks good. We 
should add a third field to show the chip load per tooth. The user 
should be able to change this load and have the feed and speed adjust 
automatically. The editor should be able to adjust the computation so 
that the maximum feed or speed is not exceeded. The editor should be 
able to perform its calculations using the as-planned or actual 
number of flutes on each tool.

We reviewed the new data for the Boxy part. Version 7.19 of the 
STEP-NC Explorer is able to simulate the machining of this part. The 
simulation is for a four axis machine and requires the Negative A 
trunnnion to be selected as the machine tool. To avoid collisions the 
part must be moved by 0.1 meters in the Z direction using the 
Motion/Adjust Mounting Placement command.

For the Bath meeting we would like to be able to simulate the 
machining of this part on 3-axis and 5-axis machines. STEP Tools is 
working to extend the explorer so that end users can create new 
workplans, move workingsteps between workplans and define setups for 
the workplans. A suggestion was made that it might be possible to 
define a function to create the setup's automatically using the 
orientation of the machine being featured and/or the orientation of 
the toolpaths.

We discussed the CAD models for the two parts. We decided that the 
dimension annotations for the tools in Moldy should be shown as mm 
values instead of inches because the numbers are more logical in 
these units. We decided that GD&T data should be created for the 
in-process models in the Boxy. A pdf file showing these dimensions is 
on the ftp site.

We reviewed the draft agenda for the Bath meeting. Several minor 
changes were made and the Meeting Invitation and Registration Forms 
are now in preparation.

The next conference call will be at the regular times on Wednesday August 26.

Action items
------------------
1.   STEP Tools to add chip load per tooth functionality to the feed 
speed editor of the Explorer.
2.   STEP Tools to add functionality to allow users to create their own setups.
3.   Boeing to change dimensions of tool annotations in Moldy to mm.
4.   KTH and Boeing to create GD&T data for the Boxy in-process models.
5.   STEP Tools and U.Bath to prepare the meeting invitation and 
registration form.
