The very first step of the production process of article of jewelry is conceptualization, creation and designs a detailed technical drawing of a Jewellery Article. The professional jewellery designer who is trained on architectural and functional knowledge of materials, fabrication techniques, composition and the design is wearable and marketable creative art.
Sri Lankan has gained recognition for its traditional handmade jewellery since ancient times. As an object of fashion, it is interesting to note that jewelry design has remained relatively constant over the years. The fundamental references, production techniques, and materials from ages ago are still being used to this day. Yet the recent rapid developments in technology and machinery have allowed artists easier alternatives to some of the old methods. These advancements have also transformed the significance and social weight jewelry holds.
Traditional hand-drawing and drafting methods are still utilized in designing jewelry, particularly at the conceptual stage, but a shift is taking place to computer-aided design programs. the traditionally hand illustrated jewel is typically translated into wax or metal directly by a skilled craftsman, a CAD model is generally used as the basis for a CNC cut or 3D printed 'wax' patter to be used in the rubber molding or lost wax casting processes.
CAD / CAM Design
CAD/CAM (computer-aided design and computer-aided manufacturing) refers to use of computer systems to assist in the creation, modification, analysis, or optimization of and manufacture of jewellery articles. CAD software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. CAD output is often in the form of electronic files for print, machining or other manufacturing operations.
CAD/CAM applications are used to both design a product and program manufacturing processes, specifically, CNC machining. CAM software uses the models and assemblies created in CAD software to generate tool paths that drive the machines that turn the designs into physical parts. CAD/CAM software is most often used for machining of prototypes and finished parts.
CAD software for mechanical design uses either vector-based graphics to depict the objects of traditional drafting, or may also produce raster graphics showing the overall appearance of designed objects. However, it involves more than just shapes. As in the manual drafting of technical and engineering drawings, the output of CAD must convey information, such as materials, processes, dimensions, and tolerances, according to application-specific conventions.
