The latest data is
at:ftp://www.steptools.com/private/Dallas/20071017_data/<br><br>
There are three AP-238 data sets:<br><br>
Dallas_Sandvik2.238<br>
Dallas_Boeing.238<br>
Dallas_Boeing_andSandvik.238<br><br>
The last file combines the first two using a STEP-NC Selective. A
machining organization can choose between the two workplans in this
selective and then inspect the result using the common inspection
plan.<br><br>
The Sandvik data has been machined. Images of the part after both the
roughing and finishing can be found on the ftp site. Videos of the
machining and on-machine inspection are in the videos sub-directory. The
times for the machining are as follows:<br><br>
<font size=2>3-axis machining (9.5 minutes):</font> <br>
<font size=2> -1st rough (44mm diameter tool), 6.5 minutes at
n=7958rpm and vf=8356mm/min</font> <br>
<font size=2>- 2nd rough (20mm diameter tool), 3 minutes at n=7958rpm and
vf=2858mm/min</font> <br><br>
<font size=2>5-axis machining (35.5 minutes):</font> <br>
<font size=2>-semi finish (16mm diameter, 4mm radius), 19 minutes at
n=10,000rpm and vf=1,974mm/min</font> <br>
<font size=2>-finish, (16mm diameter, 4mm radius) 16.5 minutes at
n=10,000rpm and vf=1,974mm/min</font> <br><br>
This is much faster than the Ibusuki demonstration because of the larger
tools. The main directory contains Fanuc (3-axis) and Heidehain 5-axis
codes for the machining and a DMIS file for the inspection.<br><br>
There was an extensive discussion of the inspection issues on both the
CMM and the CNC. For the CNC it was decided to use the Heidenhain macro's
to probe the round hole. For the CMM inspection it was decided to run the
CMM in DMIS Program mode. More data has to be added to the DMIS program
to enable a complete analysis of the measurement results. The STEP-NC
team will work with the HiPP team until all the required information has
been extracted from the AP-238 file. Where items are missing they will be
identified so that the can be added to HiPP extensions for Edition 2 of
AP-238.<br><br>
Boeing has partially converted its tool paths to STEP-NC and is
optimistic that it will be able to machine the part before the
demonstration. NIST has scheduling difficulties and will only be able to
complete the 3-axis roughing operation before the demonstration.<br><br>
