We agreed to use the 3-axis version of Boxy with 12 setups for the tool 
wear demonstration.

There were questions about the dimensions of the stock and how many of 
the setups should be included in the demonstration. We agreed that these 
issues should be resolved after the material and tools have been 
selected so that we can estimate how much material must be removed to 
get measurable tool wear. The team is reluctant to use titanium because 
of safety issues. An alloy of stainless steel was suggested and Bengt 
Olsson of Sandvik was tasked with selecting a material by January 27.

NIST has a Mitutoyo UMAP probe that should be suitable for measuring 
actual tool wear at the demonstration. In order to verify the 
measurement process Mitutoyo needs STEP models of the tools to be sent 
to its Chicago office.

NIST has a dynamometer that can be used to measure the cutting forces. A 
discussion of how to use this device was sent in a separate message.

The next call will be at the regular times on Wednesday February 3rd. A 
video of this call and the last call are now on the ftp site.
