We discussed the goals of the demonstration and how to make the
machining more flexible for a wider range of machines.
The goal is to show the part being machined and inspected from many
different data sources on many different machines. We want to show
that the STEP-NC data can be constructed using many techniques, that
it can drive many different types of machines and cutting tools, and
that the correctness of the final part can be measured using many
different methods.
At the demonstration in Dallas we want to show one, two or three
machines executing different snapshots of the process (roughing,
finishing and inspection), and we would like to compare the
inspection results data from all of the locations for accuracy.
Ideally the machines at Dallas will each show a process developed at
a different location. For example, roughing developed at GDLS or
Sandvik, finishing developed at Boeing or Airbus, and inspection
developed at NIST or Lockheed.
To make the machining more flexible we should provide a wider
selection of tool paths suited to a wider range of machines. For
example, Sandvik can use UGS to create tool paths for a large tool
machine, NIST might use Pro/Engineer to create tool paths for a small
tool machine and Airbus might use Catia to create tool paths for a
high speed machine.
To make the machining more flexible we should define features that
allow more of the volume to be removed during the roughing phase. An
action team consisting of NIST, SCRA and Sandvik was formed to define
an AP-203 model for the part before and after the roughing process so
that better features can be defined.
In summary the key differences between the Ibusuki and Dallas
demonstrations will be as follows:
1. The tolerances to be measured will be defined using an AP-224 file
disguised as an AP-203 e2 file.
2. More of the part will be defined using features and more volume
will be removed during the roughing process
3. There will be a selection of different finishing tool paths suited
to different machine tool / cutting tool combinations
4. Several CAD and CAM systems will be used to make the data.
5. The inspection process will be more flexible and allow multiple
methods to be used to measure the part (TBD).
