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.<br>

<br>
The cutting tool discussion was very extensive (more than 90 minutes)
so there was not much time for the other agenda items.<br>
<br>
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.<br>
<br>
Boeing and NIST will machine the boxy part this weekend and give
feedback on the next conference call.<br>
<br>
The next call will be at the regular times on <b>Wednesday May 19</b>.
