本研究はCADデータに基づいて鍛金加工の数値制御化を試み,塑性変形型ラピッドプロトタイピングの開発を目指すものである.本報ではハンマリングによる鍛金加工の加工特性を解析するために鍛金加工用CAMを試作し,種々の形状において成形実験を行い,その変形挙動と張り出し限界を考察した.またそのデータに基づきハンマリング工具経路の評価を行ったので報告する.
This study proposes an automation of metal hammering system on the basis of CAD data and a trial development of a forging type rapid prototyping system. In this article, a cam system for metal hammering is developed. And experiments of incremental metal hammering based on the CAD data are examined to analyze the phenomenon in metal hammering working as one of a sheet metal forming processes by use of the CAM system under several conditions. From the experimental result, the deformation behavior and the forming limit are considered. Farther more, to control the strain distribution on the workpiece, which depends on the mode of the tool path can improve the forming limitation is found.
