Unsupervised Classification of Surface Defects in Wire Rod Production Obtained by Eddy Current Sensors

An unsupervised approach to classify surface defects in wire rod manufacturing is developed in this paper. The defects are extracted from an eddy current signal and classified using a clustering technique that uses the dynamic time warping distance as the dissimilarity measure. The new approach has been successfully tested using industrial data. It is shown that it outperforms other classificat...

Development of Surface Inspection System for Wire Rod

This paper introduces the surface inspection system for wire rod in steel-making industry. The inspection system is based on vision technology. We have developed illumination system with blue LED lighting sources to get best quality of surface image. And we have implemented defect detection algorithms based on block sigma transform which can recognize wire rod objects and segments defect candid...

On-line Classification of Surface Defects in Hot Rolling Processes

This paper develops a methodology for the online classification of different types of surface defects in rolling processes. The method developed consists of three major steps: feature generation, feature selection, and classifier design. Based on the engineering knowledge of rolling processes, a set of potential features are generated from the local regions of sensing images that contain the su...

Investigation and Simulation of Wire Non-Asymmetric Rolling Process

The non-asymmetric rolling process of copper and brass wire has been simulated with the Abaqus software. Presented finite element model in this simulation of rolling predicted output curvature and contact surface width in the non-asymmetric mode (in equality of diameter of rollers, the rotational speed of the rollers and the rollers’ surface finish). The material used in this research has strai...
