We discussed progress on implementing the STEP-NC translators.
Siemens has delivered the prototype of its translator to Sandvik and
KTH for testing. Boeing has delivered its code for Catia to STEP-NC
translation to Dassault.<br>
<br>
We discussed the agenda for the face to face meeting on June 24 and
25. Four pilot projects are being formulated to test the new
translators:<br>
<br>
1. The Supply chain pilot will demonstrate the value of sending
STEP-NC data to the supply chain for bidding and production. This
pilot will measure the reduction in the data preparation costs and
the improvement in the time and quality of responses when requests
for quotes and manufacturing orders are sent to suppliers as STEP-NC
data packets.<br>
2. The on-machine acceptance pilot will demonstrate the value of
using STEP-NC to validate part quality in-situ on the machine tool.
This pilot will measure the reduction in cycle time, the reduction
in wastage, and the enhancement of manufacturing flexibility when
machining and measurement are integrated on the control.<br>
3. The tooling solution pilot will demonstrate the value of
including process solutions with tooling recommendations. This pilot
will measure the reduction in the total cost of ownership when
better quality solutions are recommended by the vendor with process
data that enables rapid, reliable deployment.<br>
4. The open simulation pilot will demonstrate the value of an open
framework for manufacturing simulation and verification. This pilot
will measure the reduction in setup time, and the enhancements to
flexibility, accuracy and safety when manufacturing requirements
(PMI), manufacturing processes and manufacturing resources can be
plugged into a common, open framework.<br>
<br>
The date of the face to face meeting has now been fixed to be June
24 and 25. A registration form has been posted to the web site along
with the enhanced agenda. The deadline for registration is June 10
but earlier responses will be much appreciated.<br>

We discussed publicity for the meeting. Modern Machine Shop has
requested an update on STEP-NC. Sandvik has recently published an
article describing ISO 13399 and its relationship to STEP and
STEP-NC.<br>

<br>
The National Tool Manufacturing Association (NTMA) has expressed an
interest in participating in the pilots but key members of their
association will require Pro/Engineer to support STEP-NC.<br>
<br>
The remainder of the meeting was devoted to a second review of the
STEP data format (Part 21). The current draft, the slides given and
a new environment for testing the specification can be found on the
following page:<br>

The new Part 21 format will be upward compatible with the current
format and enhance it to include URI's and intelligent interfaces.
The current data format has been highly successful with nearly every
CAD, CAM and BIM vendor implementing the required interfaces for the
STEP, STEP-NC and IFC (building construction and maintenance)
models.<br>
<br>
The new edition seeks to build on this success by enabling the crowd
sourcing of massive product models. The key features of the edition
include:<br>
<br>
1. Anchor and reference sections to enable the distribution of an
information mode between files linked by URI's.<br>
2. Enhancement of the base character set to support UTF-8 for
international language support<br>
3. ZIP archive support for selective updates, simple data management
and easy e-mailing.<br>
4. Time stamps and integrity locks for safe management of data sets
distributed across the supply chain<br>
5. JavaScript binding to automate the linking, simulation and
verification of the massive product models.<br>
6. Data relaxation and tagging for a new and more efficient style of
application programming.<br>
<br>
Part 21 Edition 1 has served the community well for over 20 years.
The desire is for the new format to serve us equally well for the
next 20.<br>

May 1st.<br>
