New data for the Moldy part has been created by Boeing and posted to 
the web site by STEP Tools. The new data uses AP-203 e2 annotations 
to document how to set up the stock and the cutting tool 
requirements. It also uses colors to show how many flutes are on each tool.

STEP Tools has put a no-license version of the STEP-NC Explore onto 
the web site so that others can machine the part. This version can 
perform all of the functions of the regular version but it will not 
save data so it cannot be used to make new STEP-NC files. You can use 
it to read the Moldy files or any of the other parts in our library 
and you can generate G-codes for those files using the File/Export 
code command.

Methods for changing the feeds and speeds in the AP-238 data to meet 
the requirements of the host machine were discussed. Sandvik has 
developed a powerful DLL that considers many of the options. STEP 
Tools was concerned that this DLL could not be integrated into the 
STEP-NC explorer before the next conference call. David Odendahl 
suggested a simple editor might be able to provide a solution. This 
editor would let the end user change the feeds and speeds by keeping 
the chip load constant while varying the spindle speed and number of 
flutes on each tool.

Boeing is going to test the new Moldy data in the next two weeks by 
machining the part. They will try changing the number of flutes on 
one of the tools.

The Boxy part was discussed. There was agreement that three STEP 
files need to be developed. The first file will describe the AS-IS 
model for the first set-up. The second file will describe the TO-BE 
model for the first set-up and the AS-IS model for the second set-up. 
The third file will describe the TO-BE model for the second set-up.

When this data has been developed STEP Tools will assemble a STEP-NC 
file with the three STEP models and the machining processes for the 
two set-ups.

The next conference call will be at the regular times on Wednesday July1
