Often times milled parts are designed around their ability to be fixtured within a machine tool. This paper looks at the plausibility of developing work holding methods for parts with abnormal geometry. A process was developed for three parts of increasing complexity with each part representing a grade of part that one might encounter. A 3D printed negative mold of the part with vacuum ports was developed and examined for feasibility in workholding. The process includes coatings to better seal the fixture and adapt an additively manufactured part for the purpose of workholding. The process was tested and conclusions were drawn based upon the quality of the finished part, the ease of the process, and visual keys during machining.
