As a result of a meeting, held in the US in September 1998, pilot projects will begin in the US. They are likely to include controller testing at Lawrence Livermore Labs and the National Institute of Standards and Technology (NIST), database testing at STEP Tools, Inc., and end-user functionality testing at Boeing, General Motors and General Dynamics Land Systems.
A special interest group met for the first time at the ISO STEP meeting in Beijing, China in October 1998. The United States, the STEP special interest group and the Japanese project all want to integrate the STEP-NC models more closely with STEP. The US representatives are particularly keen to make the new stand as data driven as possible and to show that a data pipeline can be constructed to take AP-203 design data, annotate it with AP-224 manufacturing feature data, compute process plan dependencies, and output the result as an AP-213 file for the macro process plan with references to ISO 14649 files for the individual machine tool working steps.
