Every year the WPI Manufacturing Laboratories manufactures medallions for Alumni weekend. The current system requires many valuable man hours to function. Creating an automated system to laser mark the medallions would improve the current medallion production system. The goal of this MQP is to use Axiomatic Design to design a mechanical system that would enable automated laser marking to be done safely inside the CNC Machine tool that finishes the medallions. Several candidate designs were evaluated based on their information content and uncertainty. Using a single slide and a galvo laser significantly reduced the information content of the system. This system will be adequate for marking and engraving. Thus it is potential starting point for integrating other manufacturing process.
