Welcome
STEP-NC is a standard developed by the International Organisation
for Standardisation (ISO) to bring CAD/CAM data into the CNC. It is
intended to replace G codes with a richer data set, including features,
geometry and tolerances.
The expected benefits of STEP-NC are the elimination of
machine-specific post processors, better accuracy and performance management,
and less waste due to better data for the machinist.
STEP-NC is a new standard, and commercial support in CAD,
CAM and CNC systems is just becoming available. See the FAQ
for more details on STEP-NC.
Upcoming Meetings
At the ISO TC184 SC4 meeting in Toulouse, France we will be conducting
demonstrations of STEP-NC for aerospace machining.

montage_0608.piz, the fishhead
part redesigned for clamping along the top and bottom edges, with
new stock with an offset of 7 mm from the finished shape. The
archive includes the Catia CATPart and CATProduct files, the STEP
files, and some JPEG images.

demo_20060523.piz, the shortened
fishhead part that fits with the rotary plate of the DMU50. The
zipped file contains the shortened fishhead CATPart; the DMU50
rotary table CATPart; a powerpoint showing the proposed position
on the table and a picture of the cutting tools we used in the
previous CATIA process (Airbus proposes to use a diameter 32 instead
of the diameter 50 for countouring); and a draft of the schedule
for the demonstration.
Change the suffix from .piz to .zip before extracting.

ensemble_ebauche.piz, the
zipped file for the demonstration. Contains, ensemble_test.CATProduct,
brut.CATPart, table_DMGv2.CATPart, rehausse.CATPart, aerospatial_test.CATPart
and ensemble_test.jpg.
Change the suffix from .piz to .zip before extracting.
