AI Technical Summary
Technical Problem
Tool marks occur on metal plates during sequential forming due to the shape of the tool tip, which affects the quality of the formed product.
Method used
The sequential forming tool employs an elliptical curve tip with a continuously changing radius of curvature, maintaining the minor axis parallel to the central axis, and a hard film coating to reduce friction, ensuring the tool maintains a constant orientation relative to the metal plate, thereby preventing tool marks.
Benefits of technology
This configuration effectively prevents tool marks on the metal plate, ensuring a smooth and high-quality three-dimensional forming process without the need for tool replacement.

Abstract
To prevent or suppress formation of a tool mark in incremental forming.SOLUTION: According to the present invention, in incremental forming in which an incremental forming tool T is pressed against a metal sheet W whose periphery is held and moved to gradually deform the metal sheet in a sheet thickness direction and form the metal sheet into a final shape, a distal end has a continuous R shape on a long axis side of an elliptic curve in a cross section along a central axis, and a short side axis of an elliptic shape has an elliptic shape parallel to the central axis.SELECTED DRAWING: Figure 1
