Relevant material characterization for load prediction in incremental forming

Robotic incremental sheet forming has arisen a recent industrial interest, as more flexible and cost-effective solution to the process using rigid computer numerical control (CNC) machines. However, prediction of loads final geometry coupled an elastic modeling robot is essential optimize trajectory thus ensure geometrical accuracy part. Within this context, aim study investigate load in case single point commercially pure (CP) titanium alloy sheet. The mechanical behavior characterized at room temperature under two strain states, i.e., uniaxial biaxial tension, truncated cone same material obtained by forming. A 3D cell records all components applied during part laser scanned end process, though still clamped along outer edge. model developed assuming some symmetries reduce computational time. influence hardening law, either identified from or tensile tests, on investigated, with focus path
