Sandvik delivered STEP models for their recommended cutting tools with 
feed and speed selections in a spread sheet in the following ZIP.

ISCAR gave us a demonstration of their tool library system and delivered 
a spreadsheet with their feed and speed recommendations.

KTH will now create a set of cutting tools for the demonstrations by 
mixing components from the two sets of cutting tool selections.

The new cutting tools will be made as STEP assemblies containing the 
required tolerances and the component selections. The new STEP files 
will then be sent to STEP Tools for splitting. In order to split, STEP 
Tools will need to implement a method for referencing the the geometry 
of the components from the toleranced assembly. Several methods for 
splitting STEP files have been discussed in the CAX-IF forum, LOTAR and 
at other venues. STEP Tools will examine these methods and select what 
seems to be the best method for the cutting tool demonstration. We will 
then demonstrate the chosen method at a new joint meeting that is being 
scheduled by Wg11 for the afternoon of Monday June 11.

We discussed the demonstration project schedule. KTH has modeled the 
positional accuracy of its machine tool and they will share the new data 
with NIST in a conference call on Friday. Now that the cutting tool 
recommendations have been made KTH can complete the STEP-NC program.

Action Items
-----------------
1. KTH to complete the STEP-NC program.
2. KTH, Sandvik and ISCAR to create cutting tool models from the STEP 
data supplied by the cutting tool vendors.
3. KTH and STEP Tools to complete the fixture model
