Abstract
Official abstract text for this publication.
A metal member manufacturing method according to one form of this disclosure is a method of manufacturing a metal member that is thinner at some portions than at other portions. The method includes a formation step of pressing one surface of surfaces of a metal workpiece that are perpendicular to a thickness direction with a press-working die so as to form a raised portion in the other surface, and a cutting step of moving a cutting blade along the other surface to cut off the raised portion by shaving. In the formation step, the raised portion is formed such that the area of a cross-section of the raised portion that is parallel to a moving direction of the cutting blade and perpendicular to the other surface decreases toward an end of the raised portion on a rear side in the moving direction of the cutting blade.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of manufacturing a metal member that is thinner at some portions than at other portions, the method comprising: a formation step of pressing one surface of surfaces of a metal workpiece that are perpendicular to a thickness direction with a press-working die so as to form a raised portion having a first raised portion and a second raised portion in the other surface; and a cutting step of moving a cutting blade along the other surface to cut off the raised portion by shaving, wherein the first raised portion is thicker than the second raised portion and the second raised portion is arranged before the first raised portion in the moving direction of the cutting blade so that the cutting blade initially comes into contact with the second raised portion during the cutting step. 2. The metal member manufacturing method according to claim 1 , wherein in the formation step, the second raised portion is formed to decrease in thickness stepwise from the first raised portion. 3. The metal member manufacturing method according to claim 1 , wherein in the formation step, the second raised portion is formed to decrease in thickness along a curve from the first raised portion.
