Ten or more of the regular participants in these conference calls
will be at the STEP meeting in Stockholm so we estimated that the
room for the STEP-NC review on Tuesday should be able to hold 20
persons and the room for the Industry review day should be able to
hold 30 persons.<br>
<br>
As per the schedule, Wg3/T24 (aka STEP-Manufacturing) will meet on
all five days of the STEP meeting. Monday will be spent meeting with
other groups, Tuesday will be dedicated to a review of the STEP-NC
resources, Wednesday will be the STEP industry day organized by SC4
with contributions by several of our team members, Thursday will be
the day of the STEP-Manufacturing machining demonstrations at KTH,
Friday will be an industry review day in which recommendations will
be made for cutting tool and machine tool data.<br>

<br>
If you can only join us for one day then Thursday is recommended,
those who can manage two days are recommended to join us for
Thursday and Friday.<br>
<br>
We discusses an assembly scenario for cutting tools in which the
cutting tool components are stored in vendor managed tool libraries
and the end user creates cutting tools assemblies from those
components. Many different scenarios can be envisaged with single
level assemblies and multi-level assemblies being managed by both
the cutting tool vendors and the end user organizations. We agreed
to develop an experiment in which cutting tool data is created in NX
from data supplied by the vendors and then the result is stored as
an assembly at the end user organization containing references to
the "master" data in vendor tool libraries and with tolerance
constraints defined on the key attributes of those components and
the assembly in the assembly file.<br>

We discussed the project schedule. More time will be needed to make
the cutting tool recommendations for the crown wheel part.
Adjustments were made to the schedule to allow one more week for the
cutting tool recommendations.<br>

Action Items<br>
-----------------<br>
1. Tooling vendors to make cutting tooling recommendations for the
crown wheel part.<br>
2. STEP Tools to create multi-level assemblies.<br>
3. KTH to define constructive geometry for cutting tool tolerances
in distributed assemblies<br>
