板料渐进成形（ISF）是一种面向个性化、小批量生产的制造技术。在这项技术提供的机会中，有可能缩短爬坡时间，并通过一台机器设置覆盖整个钣金件生产链。由于最近的工作表明，工业零件的制造是可行的，精加工操作，如翻边和修剪获得的重要性。本文首次介绍了利用ISF进行拉伸和收缩翻边的工艺性能。由于局部成形区的存在，周围没有用于ISF的夹紧装置，导致不同的材料流动行为。分析了刀具轨迹特性、法兰长度和半径对加工的影响，建立了加工窗口。
ncremental Sheet Forming (ISF) is a manufacturing technology for individualized and small batch production. Among the opportunities this technology provides there is the possibility of a short ramp up time and to cover the whole production chain of sheet metal parts by one machine setup. Since recent works showed that manufacturing of industrial parts is feasible, finishing operations such as flanging and trimming gain importance. This paper shows first works on the technological capabilities of using ISF for stretch and shrink flanging. Due to the localized forming zone the absence of surrounding clamping devices for ISF results in differing material flow behaviour. The influences of tool path characteristics, flange length as well as radii are analysed to set up a process window.
