We will use the three axis version of the Boxy part for the tool wear
demonstration.<br>
<br>
To run the demonstration we must add curve data to the tool paths for
the cross-section area, axial depths and radial depths. Sandvik will
compute this data using Vericut. <br>
<br>
To verify the computations will measure the cutting force during
machining using a Dynamometer. NIST will investigate whether one can be
made available with an MTConnect interface.<br>
<br>
To show tool wear during the demonstration we must machine at high
speed using a hard material. There was concern about the cost of
Titanium but it is the most relevant material for the aerospace
industry.<br>
<br>
We were unable to discuss the process planning demonstration due to
snow in the UK.<br>
<br>
We reviewed the testing history slides and additions were made to the
list of participants for the Springfield and Toulouse demonstrations.
There was a request to add additional material to the slides in the
form of notes and to show system diagrams for more of the
demonstrations. A new version of the slides has been posted. (Warning
the pdf version has a minor page size issue)<br>

Additional material on the history of our STEP-NC testing is on the
STEP Tools web site (see the box on Milestones).<br>

The next call will be at the regular times on Wednesday January 20th.
We apologize for not making a video of the call due to Sweden being on
vacation.<a class="moz-txt-link-freetext"
