In this research, a systematic reverse engineering, re-engineering, and fast manufacturing RRF process has been developed and validated. Commercial off-the-shelf COTS software tools and equipment that support the RRF process have been identified, evaluated, and tested. An integration framework has also been developed and employed to create an RRF testbed. This testbed constructed using COTS software and equipment supports three major engineering tasks the reverse engineering that supports recovering of technical data from worn sample parts, re-engineering that alters design for better performance or lower cost, and fast prototyping that incorporates advanced manufacturing technologies to produce functional or physical prototype of the part in small quantity in a short turnaround time. A number of examples obtained from logistics centers have been employed to illustrate and demonstrate the capabilities established in the RRF testbed. This testbed allows a geographically distributed team to work on a design task both synchronously and asynchronously. This testbed was presented and demonstrated to OC-ALC personnel on November 30, 2005, and received very positive feedback and excellent suggestions.
