This gear box part was originally developed by KTH and was enhanced and manufactured by the STEP-NC Machine Development Partners during the Renton testing round in October 2010. It was also used during the earlier NIST 2010 and Bath 2009 testing rounds.
Boxy is designed to exercise setup compensation and multiple setups. The file contains sets of alternative workingsteps for doing operations with different tools, as well as a full selection of in-process models for the results of each operation and the delta volumes. Below is the latest version.
This files below were created for earlier testing rounds. Renton file was designed for seven setups on a three-axis machine. The work coordinates are set so that they align with a known corner of the material. The NIST is a seven setups, three-axis program similar to the Renton file, but without any setup compensation. The Bath files are three different versions with setups designed for three, four, or five axis machining.
2016-01-08 - Updated the five axis version to include the latest STEP-NC capabilities. This was used for a 5-axis MTConnect machining and measurement demonstration in October 2016.
