STEP Tools has ported its STEP-NC export functionality to Mastercam X7.

Sandvik has made cutting tool assembly data for the Boeing/Okuma tools 
and the Hermle/KTH tools.

We discussed the generation of in-process models for the male and female 
parts of HARDMOLDY. The raw toolpath data is misleading because it is 
too process specific. We need geometry that is more descriptive of the 
target area showing the limits of what must be cut without requiring 
specific results. We will try to generate this geometry using an 
extrusion or projection of the underlying part geometry.

We discussed what facilities will be necessary in a laboratory to test 
STEP-NC machining.

We discussed the Subtractive/Additive Manufacturing conference call 
between the teams developing STEP AP242, STEP-NC AP238 and AMF. There 
are concerns that because AMF approximates geometry it is less 
appropriate as a neutral data format now that boundary representations 
can be passed between systems using formats such as STEP, IGES and JT.

A recording of the call is on the ftp site.

The next conference call will be at the regular times on Wednesday 
January 22nd and will continue to be held on a weekly schedule at least 
until the Feb 13 and 14 workshop.
