KTH has produced a set of slides showing how the Boxy part can be 
machined on 3, 4 and 5-axis machines.

ftp://ftp.steptools.com/private/Bath/Boxy_Part_3,_4,_5-Axis_Machining.ppt

The STEP-NC data for the three versions is on the ftp site. The sites 
that are machining the part should begin to dry run the export codes 
for these versions. The new data includes tool paths to etch the name 
of each site onto each part.

ftp://ftp.steptools.com/private/Bath/Boxy_Part_5-Axis_Machining_2_Setups.238

These files do not include any part workpiece data. Boeing has 
prepared toleranced workpiece data for the in-process models used in 
the 4-axis machining. These models will be added to the 4-axis data 
by KTH along with un-annotated models for the 3 and 5 axis machining.

Leon Xu has sent cross section data for the Moldy part to STEP Tools. 
STEP Tools will add this data to version 5 of the Moldy part. Sites 
that want to machine Moldy for this round should use version 4 as posted below.

NIST has been able to modify feeds and speeds for the Moldy part 
using their Siemens simulator. A presentation will be prepared for 
the Bath meeting.

The last conference call before the Bath meeting will be at the 
regular times on Wednesday September 16th. A recording of this 
conference call is at:

Action items
------------------
1.   All machining sites to dry run the data
2.   STEP Tools to fix some code issues identified by KTH for arc's.
3.   KTH to assemble final versions of the Boxy data that include 
workpiece models for each stage of the process.
