Abstract
A press forming method includes a first process of obtaining a pressing force applied to each portion of a tool by an workpiece material during press forming while independently driving the respective each portion of the tool divided into multiple portions and press forming the workpiece material, and a second process of adjusting at least one of an applied driving force, an applied driving speed, and an applied driving timing for each portion of the tool to cause a processing portion of the workpiece material in which the state approaching an overload state is detected based on the pressing force to flow to other processing portions of the workpiece material.
