Analysis of continuous magnetic field-assisted double-sided incremental forming

This paper describes the analysis of continuous magnetic field-assisted double-sided incremental forming (MDSIF), a derivation of magnetic field-assisted single-point incremental forming (M-SPIF). In M-DSIF, the driving magnet remains in contact with the workpiece and does not allow for relaxation between individual steps (called contours). M-DSIF enables forming of truncated cones much faster and more accurately than M-SPIF. The number of revolutions per contour of the tool greatly impacts the resulting shape. The proposed two-step M-DSIF is a viable option for distributing material from the center toward the corners of the cone base, which minimizes localized strain in the corners.
