Dimensional Accuracy of Single Point Incremental Forming

Dimensional Accuracy of Single Point Incremental Forming (SPIF) is studied with the use of a Box-Behnken design analysis. The dimensional accuracy of this process is determined by comparing parts manufactured using SPIF with the part drawings used to create the manufacturing toolpaths. Five factors are varied in the manufacturing of the SPIF process, and they are: material type, material thickness, formed shape, tool size, and incremental step size. The Box-Behnken design analysis allows for determination of how these factors affect the dimensional accuracy.
