Title:
SEQUENTIAL SHAPING METHOD AND SEQUENTIAL SHAPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/013950
Kind Code:
A1
Abstract:
Provided is a sequential shaping method for shaping a metal plate W, being held at the periphery thereof, into a three-dimensional shape by moving the tip-end part of a bar-shaped tool T pressed against the main surface of the metal plate W. As the bar-shaped tool T moves, the metal plate W is shaped while forming a machining trajectory Fw having an amplitude H in a direction intersecting the movement direction of the bar-shaped tool T and extending along the shaping surface of the metal plate W. In this way, the machined portion along which the bar-shaped tool T has passed can be made virtually wider and tool trace can be suppressed during shaping, thus enhancing the appearance quality of the shaped product, while achieving reductions in facility expenses and manufacturing costs.
