ncremental Sheet Forming (ISF) is un-conventional metal forming operation widely used to create products with complex, free-form shapes without requiring specialized dies. The main components of this process include a sheet metal blank, a backing plate, a blank holder, and a forming tool. The blank holder secures and clamps the metal sheet during forming, while the backing plate supports the sheet to inhibit initial bend and provides an open area for forming. A CNC tool follows a sequence of contours, incrementally deforming the sheet by taking small depth steps I
