<p>Traditional single-point incremental forming (SPIF) requires no mold and allows flexible manufacturing of small quantities and variety but the surface quality of the workpieces after processing is poor, so it is not commonly used. Multi-plate incremental forming (MPIF) reduces tool wear on the workpiece surface so machining quality is increased. MPIF is complex and exhibits nonlinear characteristics so numerical simulation software is required. ABAQUS is a numerical simulation tool for the analysis of complex and nonlinear problems and is widely used in research and industry. This study uses an experimental-numerical framework to determine the forming characteristics of MPIF on AL1050 aluminum alloy plates and compares it with traditional SPIF. The results show that step depth and tool diameter significantly affect the forming characteristics of MPIF. The results also demonstrate that MPIF can be used to manufacture thin-plate parts with minimal surface roughness (SR) and efficiency in processing time is significantly increased. Numerical simulation tools address the forming force analysis problem for MPIF and can be used to analyze complex and nonlinear problems.</p>
