"Boxy" Gear Box Part

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 and Bath testing rounds.

This particular part 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 from the Renton 2010 round. It 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.

2011-11-29 - Updated to correct some XML escapes in STRL references within the data.

2011-08-25 - Updated with proper units on the cutting tool values. The previous version incorrectly had inch units on millimeter values.

This files below were created for earlier testing rounds. 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.
