Experimentation and Design of Prototype Device for Three Point Incremental Forming

Based on the principle of Single Point Incremental Forming (SPIF) and Double Side Incremental Forming (DSIF), A new Three Point Incremental Forming (TPIF) prototype device was developed to improve the forming accuracy. The mechanical structural components and the control system were designed and the TPIF prototype device was assembled. A TPIF trial example proved that this TPIF device can realize more forming accuracy than SPIF and DSIF. This TPIF prototype device provides a good platform for further study of the three point incremental forming.
