This paper proposes a unique kind of jewelry, called stretch formed jewelry. The paper presents a parametric voxel oriented approach to produce stretch forming components that are dies and punches having different patterns of designs. Stretch formed jewelry is created on thin sheet metals (gold or silver) on top of which design patterns are embossed with die and punch tools by stretching the sheet metal beyond elastic limit. Voxels are predefined small structural elements for which the user defines the key parameters. Parametric voxels can be varied during the design process and are joined together to create the design model by the use of rules. Computer-Aided Design (CAD) in conjunction with Rapid Prototyping (RP) machine generates forming tool components.

A parametric feature based jewelry modeler for designing and manufacturing of the Fret-worked bangles. These bangles are made from gold and adorned with fretwork designs. Fretwork is a decorative design that is either carved in low relief on a solid background, or cut out to adorn a jewelry item. Fretwork designs are viewed as features that are to be recurrently removed from the stock-solid bangles. The jewelry modeler supports diverse integrated manufacturing through computer controlled manufacturing. Fret-worked bangles are fabricated using rapid prototyping technique.

A parametric voxel-based jewelry modeler is developed for designing carved bangles of sophisticated craftsmanship. Carved jewelry is the form of jewelry having small internal repeated cavities as engraved with a thin sharp tool on the surface of sheet metal. The parameters ’ values are defined by the user and modeling of the jewelry design is carried out by the modeler based on the specified values of the parameters. The modeler combines multiple copies of a parametric voxel element to deliver more number of jewelry designs. Voxel is a building block of a design model and defined by parameterized geometry and attributes. A voxel library is created from which voxel elements are selected. The jewelry modeler supports diverse integrated manufacturing through computer controlled manufacturing.
