Single Point Incremental Metal Forming(SPIMF) is a process that allows architectural panels to be incrementally formed from sheet metal into doubly-curved complex shapes using a robotic arm and a stylus-like end effector. SPIMF leverages industrial robots’ precision and strength by gradually pushing the end effect or into vertically supported sheet metal.This work was inspired by Anmar Kalo andMichael Jake Newsum’s Incremental SheetMetal Forming and CITA’s Stressed Skins project. SPIMF examined how different materials, tools, and tool path generation methods impact the finished quality of completed pieces along with applications for the formed metal parts. Once an understanding of howSPIMF worked, focus was put on how to accurately program the robotic arm to produce repetitive geometries that correspond with a digital model. By creating a feedback loop that studies how the sheet metal deforms and how accurately the robot performs the forming task, new and more accurate geometry can be used to program the arm.
