Web-based Design and Manufacturing System for Micro Fabrication

마이크로 가공을 위한 웹 기반 설계 가공 시스템

In this paper a web-based micro fabrication system is discussed. A commercial CAD and a web browser were used as its user interfaces. In these user interfaces the concepts of Design for Manufacturing (DFM) was implemented providing the fabrication knowledge of micro machining to the designers. Simple databases were constructed to store the fabrication knowledge of materials, tools, and micro machining know-how. The part geometry was uploaded to the web server of this system as an STL (Stereo Lithography) format with process parameters for 3-axis micro milling. A Slice-based process planner automatically provides NC codes for controlling micro stages. A couple of micro parts were fabricated using the system with micro endmills. This design and manufacturing system enables network users to obtain micro-scale prototypes in a rapid manner.
