ELECTRIC PRESS, BEND-POINT DETECTION METHOD, AND PROGRAM

摘要

A detection unit for detecting a press position and a load at the press position; an input/storage unit for inputting and storing a value serving as a reference for determining a bend point in a relation between the press position and the load at the press position; a slope calculation unit for calculating a slope of the load based on the press position and the load at the press position, which have been detected; and a bend-point determination unit for determining a point, at which the calculated slope of the load exceeds the value serving as the reference for determining the bend point, as the bend point are provided.

1. An electric press comprising:
a detection unit that detects a press position and a load at the press position; a first input/storage unit that inputs and stores a value serving as a reference that determines a bend point in a relation between the press position and the load at the press position; a slope calculation unit that calculates a slope of the load based on the press position and the load at the press position detected; and a bend-point determination unit that determines a point, at which the calculated slope of the load exceeds the value serving as the reference for determining the bend point, as the bend point.
