Development of a New NC-Controlled Trial Manufacturing Process for Sheet Metal Forming

박판 형성을 위한 새로운 추치 제어식 시작 방법의 개발

In the work, a new computerized incremental forming method having high flexibility has been developed. In the mothod, the ordinary tools are replaced by various small tools, and only the small local region of a sheet blank is incrementally by movement of these tools. Since a small tool moves over the arbitrary surface ofthe dies using a NC machine, it is possible to produce three-dimensional and non-symmetric parts directly from CAD data. Arbitrarily shaped dies are made by LOM(Laminated Object Manufacturing), which is one of the Rapid Prototyping Methods. A forming machine is designed and developed by introducing a computer to control the movement of the tools.
