Abstract

 

In the manufacturing sector, product quality and overall reliability of business hold significant importance for customers. Many businesses employ various quality control methods throughout the production process to meet these quality and reliability requirements. However, existing processes are predominantly carried out manually, leading to issues such as human error, time inefficiencies, and reduced accuracy. To overcome these challenges and prevent the recurrence of errors, the establishment of continuously learning automated control systems has become indispensable for contemporary businesses. In this study, deep learning techniques were utilized with the aim of eliminating common errors encountered in manual quality control processes and automating the procedure. Within the scope of this study, an analysis was conducted to identify various types of errors present in the final product, using deep learning algorithms. The dataset used for this research was obtained from the Kaggle platform. This publicly accessible dataset contains a total of 7095 steel plate surface images, each featuring various types of defects. The types of defects are categorized into four groups, namely Pitted Surface, Crazing, Scratches, and Patches, and all images have been pre-labeled accordingly. In this study, Convolutional Neural Networks (CNN) were employed for the automated identification of the types of defects present in the dataset. Various predictive models were developed using the CNN algorithm, and to determine the final model to be employed, several modifications were made to the dataset, including pre-processing, artificial image augmentation, and hyperparameter tuning. The results obtained from the various developed models are presented in a comparative manner. The study demonstrates that when artificial intelligence and deep learning techniques are effectively employed in the industrial production sector, error types can be accurately identified, and this will serve as a foundation for future research endeavors.
