We continued the discussion of the machining and measurement 
demonstration to be held at the Future of Flight Museum in Mukilteo, 
Washington State on October 5th.

We showed new technology developed by the Mind the Gap project for 
visualizing machining processes in smart phones and tablets. The 
demonstration was given on previously recorded MTConnect data.  The 
visualization technology is currently limited to showing 3 axis 
machining for a single tool.

For the final demonstration we will have technology that (1) optimizes 
the machining process for different tools and materials, and (2) 
measures the results of the process on a virtual CMM.

The 5-axis boxy test part has a process plan for soft materials (e.g. 
foam and perhaps aluminum). The demonstration will use titanium so the 
process must be changed. The following slides outline a plan for making 
the changes using the NC Generation service:

Testing with the Okuma at STEP Tools has shown that the machining 
process must be sampled at least every 50 milliseconds to ensure 
accuracy of the measurements.

We decided to have a technical team pre-meeting at STEP Tools on June 
14th and 15th in Troy NY to validate the development of the three 
services and their application to the demonstration.

The next meeting will be at the regular times on February 10th.

Action Items
------------------
1. Penn State to asses the practicality of the plan for making process 
changes / optimizations.
2. Boeing to determine the MTConnect sampling rate for the CNC that will 
be used for the machining.
