We discussed how to present demonstration results to the audience.
Holding a race where each contestant (process) is given five minutes
of machining time is easy to understand. The potential danger is
that the audience will forgot about the total picture including the
cost of the tooling and the cost of the tool wear. This can be
mitigated by the presenter (David Odendahl) so the script is
important.<br>
<br>
Another danger is that a direct competition between the two tool
vendors will put them under pressure to optimize speed at the
expense of every other parameter. A strategy for avoiding this is to
run the competition between the Boeing process and a single tool
vendor process. For example, on Monday there could be a competition
between Boeing and Iscar for the profiling, and between Boeing and
Sandvik for the pocketing, and on Tuesday the competitions could be
reversed.<br>
<br>
In order to run these competitions we may need to fixture up to four
copies of the part on the machine. We have 15 blanks so we will run
out if we consume 4 per day. However, there are four pockets plus
different stages to the profiling so we can run the competitions on
different stages each day. <br>
<br>
In the v5_IMTS_HARDMODLY some of the pocketing operations are
grouped: each is started together, then roughed together, and then
finished together. This is standard practice because it saves time
on tool changes. However, in STEP-NC the processing system can
determine if a tool change is necessary between operations.
Therefore, the grouped operations will be subdivided to give us the
flexibility to pick and choose between the pockets for the different
competitions.<br>
