The latest version of Boxy includes toolpaths for half inch tooling. The 
data has been simulated by Sandvik using Vericut. Boeing will compute 
Cross Section data for the new toolpaths.

KTH will create new stock models and organize the data into eight setups 
to reduce the machining time. They will add fixture models for the setups

The HiPP model extends AP-238 for inspection process planning and 
measurement using constructs originally developed for AP-203e2, AP-219 
and ISO 14649 part 16. Fiona Zhao has recently joined NIST as a guest 
researcher from the University of Auckland where she investigated the 
HiPP model as part of her Ph.D thesis research. We are hoping that she 
will be able to help us document and test the HiPP model so that we can 
make it part of AP-238 Edition 2. To make this happen we need to 
document how to use HiPP with documentation similar to ISO 14649 parts 
10 and 11 and we need to extend the AIM of AP-238 to include the 
relevant portions of the AIM models already developed for AP-219 and 
AP-203 e2.

The KTH machine tool model is being developed as a Usage Guide for 
AP-214. The model includes fixture definitions as well as machine tool 
definitions. For the machine tool model section it is using ISO 14649 
part 110 to define its requirements. The advantage of developing the 
machine tool model as a Usage Guide is that existing CAD systems with 
AP-214 translators can be used to create machines defined by the model. 
To add these models to AP-238 Edition 2 we need to extend AP-238 to 
include more of the entities in AP-214. In particular, we need to add 
the entities in the AP-214 kinematics model to AP-238. A presentation on 
thee machine tool and fixture usage guide will be given in the next 
conference call.

The desired contents of AP-238 Edition 2 will be discussed at the NIST 
meeting. To prepare for the possibility of an extended discussion, we 
will reserve the conference facilities for a third day (Friday June 18).

We talked briefly about the meeting invitation. We may want to produce 
two invitations: a one day invitation for those interested in seeing the 
demonstration, and a two or three day invitation for those who wish to 
participate in the Edition 2 discussions.

The next call will be at the regular times on Wednesday March 31st. A 
video of this call is on the ftp site.

Action Items
----------------
Boeing to prepare Cross Section data for the half inch tooling.
STEP Tools to extend the STEP-NC Explorer so that fixtures can be 
defined for each setup
NIST to reserve the conference facilities for an extra day and to 
investigate getting the government rate for the conference hotel
KTH to develop a 3 axis version of Boxy with 8 setups, fixture data and 
improved stock models
KTH to prepare a presentation on the Machine Tool and Fixture Usage 
guide for the next conference call
NIST to investigate the feasability of developing 14649 documentation 
for the HiPP model
