Single point incremental forming (SPIF) that will produce non-symmetric sheet metal parts has been rarely dealt with so far. SPIF of a Francis hydro-turbine vane made aluminum alloy is studied as typical example in this work. At first, concave geometry, encompassing the desired shape designed, from which formed part be ultimately cut out. The necessary toolpaths are created by using CAM softwar...

The present paper proposes a numerical-experimental comparative study on the single point incremental forming process. A DC04 steel sheet with thickness of 0.6 mm was used for both numerical simulation using finite element method and experimental research. type trajectory spiral finished part obtained truncated cone-shaped part. analysis program Ls-Dyna. simulations were performed in several va...

Single point incremental forming is one of the most intensely researched die-less manufacturing process. This process implies usage a CNC equipment or serial robot which deforms sheet metal with help relatively simple tool that follows an imposed toolpath. As every cold process, besides many given advantages it has also some drawbacks. One big drawback in comparison other processes low accuracy...
