Single point incremental forming is a promising sheet metal forming technique for small batch production. However, the technique is unable to manufacture vertical walls without significant thickness variation and geometrical errors. Two-point incremental forming has the capability of manufacturing vertical walls but requires actuators and intricate rig designs. This paper presents a design facilitating vertical wall manufacturing using a die similar to that used for two-point incremental forming but without actuators. The geometry is created in six passes with a toolpath that can be generated on any leading computer-aided manufacturing software. Manufacturing with this technique reduces geometrical errors in critical areas and improves thickness distribution. This research will be of interest to anyone looking to manufacture prototypes with flat-based geometries in a cost-effective manner.

单点增量成形是用于小批量生产的有希望的钣金成形技术。但是，该技术无法在没有明显的厚度变化和几何误差的情况下制造垂直壁。两点增量成型具有制造垂直壁的能力，但需要执行器和复杂的钻机设计。本文提出了一种设计，该设计使用类似于用于两点增量成形的模具但没有执行机构的模具来促进垂直壁的制造。几何图形是通过六次通过刀具路径创建的，可以在任何领先的计算机辅助制造软件上生成。使用该技术进行制造可减少关键区域的几何误差，并改善厚度分布。
