A new reformation scheme of steel bars and a learning method for various plastic characteristic using fuzzy clustering

摘要

In order to secure the precise straightness, the steel bars is reformed by bender. Up to this time, this bender has been operated by experts. However, the number of experts has been decreasing year by year. Automatic reformation is required.This paper presents a reformation scheme to cope with variations in physical characteristics of the steel bars, and an estimation method of the stress required to reform the steel bars using a fuzzy clustering method. The precision of reform experimentalso satisfies the target.
