Abstract：

For the problems of uneven load in single point incremental forming (SPIF) that caused various instability and time-consuming, two kinds of paths processing on truncated pyramid-shaped workpieces were presented on the basis of plate multi-point composite incremental forming (MPCIF). The reasonable process parameters were set by establishing two finite element models on path 1 and path 2. The simulated results of equivalent plastic strain, forming precision and wall thickness of deformed parts with path 1 and path 2 are compared and show that plate with path 1 can obtain smaller values of the maximum equivalent plastic strain and change quality of plastic deformation, more uniform wall thickness, smaller bulge in the bottom of the specimen and deviation from the theoretical outline, better shape accuracy, larger value of the minimum wall thickness and more uniform. Therefore, path 1 is more suitable for MPCIF.
