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...

superplastic materials show huge amount of deformation in low strain rates and temperature above half of melting point. in superplastic forming, estimating the pressure–time diagram and thickness distribution has significant importance. utilizing numerical methods, the involved parameters in superplastic forming can be optimized for such estimations. in the present paper, the simulation of supe...
