The STEP-NC software development continues to make good progress. A 
few remaining issues are being corrected for the graphics engine. The 
simulation software is being optimized. A new feature display pane is 
being added to the STEP-NC Explorer. This pane will offer options for 
defining feature and in-process geometries for workingsteps by 
importing AP-203 files.

Sandvik has made Vericut projects for the Impeller and KTH parts.

Larry Maggiano gave a brief presentation on the new probe scanning 
technology. The optimal angle between the probe and the part is 30 
degrees and any angle up to 60 degrees is allowed.

Peter Klein gave a presentation on how adaptive machining is 
implemented by Concepts Nrec. A grid of points is used to define a 
ruled surface. By measuring these points a difference between the 
as-designed and as-machined part can be computed and new tool paths 
can be generated that will machine the part more accurately.

For the October demonstration measurement data will be made on 
several different devices and converted into STEP-NC data. An export 
interface on the STEP-NC Explorer will be used to generate the data 
needed by Max5 so that it can send corrected paths back to STEP-NC 
Explorer for integration into the machining plan.

The focus of the demonstration will be on correcting the tip of the 
main blade.

The next conference call will be on Wednesday July 16.

Action items
------------------
Martin Hardwick to generate a spreadsheet file defining the probe 
points for the leading edge of the splitter.
Larry Maggiano to measure the blade thickness of the main blade of 
the part supplied by Sandvik
Sid Venkatesh to dry run the machining using Fanuc 160i codes
