The ibusuki5.238 file has been simulated by NIST, Sandvik and the 
University of Bordeaux. There is an issue with the position of the 
part. Sandvik estimates that the offset is wrong by 1mm in the X 
direction and 2.68mm in the Y direction. This issue will NOT be 
corrected before the machining and we will examine the results of the 
measurements to determine if they contain the same errors.

The rough part has been sent to Sandvik and the University of 
Bordeaux. The FEDEX web site indicates that the parts for Sandvik 
were delivered on Monday at 5PM and that the parts for the University 
of Bordeaux will be delivered early on Tuesday.

There was some discussion on the proper procedure for probing the 
part when only one axis has been calibrated. STEP Tools has generated 
two sets of AP-238 files. The first probes in only X or Y 
(ibusuki5.238). The second probes in X and Y 
(ibusuki5_probe_x_and_y.238). STEP Tools believes that the Heidenhain 
probing macros may be able to compensate for two direction probing by 
first rotating the table so that the probe is normal to the surface.

The three sites will machine the part this week.

The next conference call will be on Friday at the regular time (1PM 
Europe, 7AM USA, 8PM Japan).  Sandvik will host the call because they 
have a conference number that can be used for local calling from any 
country. Airbus will continue to provide the Webex site. Martin 
Hardwick will be calling in from Japan.


Action Items
------------------
NIST, Sandvik and the University of Bordeaux to machine the part and 
deliver avi or wmv files to STEP Tools.
All to consider the best strategies for measuring parts on a CNC.
STEP Tools to investigate algorithms to correct the position of the 
workpiece in an AP-238 file.

The next conference call will be hosted by Airbus on Friday June 29th 
at 8PM Japan, 1PM France, 7AM Eastern USA
