International STEP-NC Demonstration, Bath, UK 2009

On September 21-24, 2009, the STEP Manufacturing team (ISO TC184 SC4 WG3 T24) met at the University of Bath in concert with the TC184/SC1 meeting for a new round of STEP-NC international testing.

Over the course of the demonstration cycle, the "Boxy" series of data sets were developed to exercise capabilities with multiple setups. Three different versions were created, each with multiple setups designed for three, four, or five axis machining. Furthermore, each file contains a number of alternative workingsteps for doing operations with different tools. The data sets also contain a full selection of in-process models to display the results of each operation as well as the delta volumes. The full data sets are listed below along with some videos of the actual machining.
