    Estimation of the Pause Times in Cold Forging Machines by Using Data Mining Methods
    (2018) Türkoğlu, Buse; Komesli, Murat
    Within the scope of the study, a system was developed to predict the pause times of cold forging machines using data mining methods, thus increasing machine efficiency. The industrial companies are seeking solutions to remove manufacturing defects from production and to maintain their market sustainability. In order to increase productivity, all production processes must be uninterrupted. For this reason, it is imperative that the error logs of the machines used in industrial systems be converted to infortmation. This study presents and compares data mining algorithms that analyze this information to reduce the cold forging machine working pauses. The most favorable data mining methodology selected as a result of comparison has been the J48 model. It produces meaningful results for large data sets and predicts errors based on a behavioral model. Using the J48 model, 28 faults have been detected in the data set. According to the results, it is estimated that there may be a promising method to reduce the number of cold machine working pauses.
