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.

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.

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.

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.

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.
