Nowadays Single Point Incremental Forming (SPIF) is really a new technology of forming metal sheet after its formation and long development in about five decades. Although it was invented in, 1967 by Leszak, an American inventor, but the applications of the innovative technology have just been popular from 1990 because of the advance of controlling technology. This technology is especially adapted to small batch, unique or single productions. In almost all cases, the workpiece material sheets are metal such as aluminum alloys, bronze, mild steel, stainless steel and even Titanium with lot of researches, papers and thesis... Nonmetal sheets are rarely applied in this technology because of rare application. Nowadays, on the rise of the development of composite materials such as, PVC, thermoplastic resins... that have been a lot of applications on living life and technology. In this paper, we dedicate all of our work in the examination some parameters of forming that influence on the deformable ability of PVC plastic by empirical method under the support of DOE and Minitab software. This paper also provides our own experiences in forming PVC sheet that we had performed in the recent decade. |
