The Control of the Gap between Tool and Support, and the Analysis of its Effect on the Accuracy of CNC Incremental Forming

Abstract:

Two kinds of methods for the control of the gap between pressing tool head and support in CNC incremental forming have been discussed (i.e. pressing path adjustment method and support shape adjustment method), and whose effects on forming accuracy are analyzed by using the Finite Element Analyses. The methods for the generation of pressing paths and supports have been given for the two forming method of the pressing path adjustment and support shape adjustment, and the Finite Element Analysis models have been built for them respectively. The method of digital simulations for the two forming cases mentioned above based on the ANSYS/LS-DYNA software has been presented and the forming precision of the two forming methods are analyzed through the comparison of digital simulation results.
