1. Completing the round 1 machining at Boeing using the Okuma and at KTH 
using the Hermle

Boeing was able to machine the two roughing operations on its Okuma 
machine using the Iscar process before the NIST meeting. KTH has now 
machined the same operations on its Hermle machine using the Sandvik 
process.

We now need to complete the Sandvik process at Boeing and the Iscar 
process at KTH. The Sandvik process appears to have issues with the tool 
holder at Boeing, and the Iscar process appears to require stronger 
fixtures at KTH.

2. Preparation for the Machining and Modeling workshops at OMAC in 
Orlando on February 13 and 14

Registration information is now available for the two days of STEP-NC 
related workshops to be held at the OMAC meetings in Florida.

The meeting will discuss the progress of the CAM Data Exchange project 
and its application to tooling optimization for interoperable machining. 
In preparation we will extend the machine testing to include the 
roughing of the male and female sides of the mold. The meeting will 
discuss progress to date, the lessons learned and our strategy for 
optimizing the finishing operations.

3. STEP-AM model for Additive Manufacturing (ISO 14649-17) 
ftp://ftp.steptools.com/private/STEP-AM

The STEP-NC committee in ISO has released a new model for Additive 
Manufacturing. The release is timely because new machines are being 
developed that combine additive and subtractive machining by loading a 
laser into the tool head.

Tape and fiber layup also makes extensive use of tool paths in their 
manufacturing processes. Using STEP geometry for additive machining will 
enable more accurate results, reduce data volume and enable the 
integration of additive and subtractive manufacturing.

STEP-NC AP238 is an integrated model for applying STEP-NC processes to 
AP242 designs. This includes the definition of setups in workplans, the 
definition of tooling in workingsteps, and the definition of processes 
in toolpaths. We need to liaise with the ISO team developing STEP-NC 
Part 17, and the LOTAR team gathering requirements for edition 2 of AP242.

4. Changes to the licensing for ST-Machine and ST-Developer

Now that Boeing is in development to use AP238 in production processes, 
we are anticipating an exceptional year for STEP in Manufacturing. 
Therefore STEP Tools is making two changes to its licensing policies. 
The first is to remove the Gcode restrictions in ST-Machine. The latest 
version will generate codes for a wide variety of machines.

The second change is to make a node locked version of ST-Developer 
available for research, testing and teaching. The new personal edition 
of ST-Developer will be put onto the STEP Tools home page as soon as it 
is available.

A recording of the call is on the ftp site.

The next conference call will be at the regular times on Wednesday 
January 15th one week earlier than usual.

Action Items
------------------
1. Boeing to machine the profile and pocketing operations using the 
Sandvik process
2. KTH to machine the profile and pocketing operations using the Iscar 
process
3. Sandvik to create ISO 13399 data for its tool assemblies
4. David Odendahl to prepare in-process models for the male and female 
roughing.
5. Bob Lipman to organize a telecon on Part 17 with the team developing 
requirements for AP242 edition 2.
