We had an extensive discussion on tool requirements. The STEP-NC data is 
very prescriptive and seems to require the machinist to select tools 
with exactly the specifications given in the AP-238 data. This is not 
true and in many cases a wide range of tools would be acceptable but the 
range is not being documented in the STEP-NC data. We agreed that the 
cutting tool model in AP-238 should be enhanced to show the range of 
acceptable values for each parameter and where reasonable give reasons 
for the ranges. Fred Proctor agreed to make a draft and one has been 
posted at the following address.

The cutting tool discussion was very extensive (more than 90 minutes) so 
there was not much time for the other agenda items.

We agreed that there will be no registration fees for this meeting with 
contributions for break refreshments being made on a voluntary basis. We 
reviewed the agenda and made some minor changes in the time available.

Boeing and NIST will machine the boxy part this weekend and give 
feedback on the next conference call.

The next call will be at the regular times on *Wednesday May 19*.
