Description
I conducted this qualitative research including data collection, data analysis and comparison analysis in a Casting and Jewelry Techniques course at Arizona State University for a whole semester. The purpose of this research was to explore the symbolic interactive meaning of metalworking to university students in metal courses, and if they had various learning needs to improve and enhance their metal art making by seeking their responses to the relationship between technical issues and concepts of their own artworks. The study results showed that the meanings of metalworking to students were craftsmanship, and a sense of accomplishment, and it related to their daily lives in career and presentation. Most of them focused on the degree of technical completion and forms of work rather than expressive concepts, and techniques were important in their works. I compared my findings in this study with my pilot study and James's study in a sculpture studio class, and found some similarities in teacher's philosophy and students' metalwork meanings that included career aspirations, some peer interaction, technical concerns rather than concept formation, and process as serious play or the exploration of materials.

DescriptionDuring my summer internship at a major cable TV network, I pitched the network various show concepts for new reality TV programming. Since then, I have created my own casting company in order to continue developing these shows by casting nationwide for talent.

Description
When manufacturing large or complex parts, often a rough operation such as casting is used to create the majority of the part geometry. Due to the highly variable nature of the casting process, for mechanical components that require precision surfaces for functionality or assembly with others, some of the important features are machined to specification. Depending on the relative locations of as-cast to-be-machined features and the amount of material at each, the part may be positioned or ‘set up’ on a fixture in a configuration that will ensure that the pre-specified machining operations will successfully clean up the rough surfaces and produce a part that conforms to any assigned tolerances. For a particular part whose features incur excessive deviation in the casting process, it may be that no setup would yield an acceptable final part. The proposed Setup-Map (S-Map) describes the positions and orientations of a part that will allow for it to be successfully machined, and will be able to determine if a particular part cannot be made to specification.
The Setup Map is a point space in six dimensions where each of the six orthogonal coordinates corresponds to one of the rigid-body displacements in three dimensional space: three rotations and three translations. Any point within the boundaries of the Setup-Map (S-Map) corresponds to a small displacement of the part that satisfies the condition that each feature will lie within its associated tolerance zone after machining. The process for creating the S-Map involves the representation of constraints imposed by the tolerances in simple coordinate systems for each to-be-machined feature. Constraints are then transformed to a single coordinate system where the intersection reveals the common allowable ‘setup’ points. Should an intersection of the six-dimensional constraints exist, an optimization scheme is used to choose a single setup that gives the best chance for machining to be completed successfully. Should no intersection exist, the particular part cannot be machined to specification or must be re-worked with weld metal added to specific locations.
