Comprehensive Analysis of Abnormal Assembly Situations Encountered in Automatic Screwing Processes This article examines in detail an abnormal assembly situation that can be encountered in automatic screwing processes commonly used in electronic device manufacturing. It analyzes whether a screw with a higher hardness than the case can leave deformation on a phone case made of Aluminum alloy (ALS36) as material and whether a significant angular deviation occurs during screw assembly. During this article, the ductility of ALS36 is determined and the material undergoes plastic deformation. The possible causes of this abnormal situation, related engineering principles, material properties and possible deviations in manufacturing processes are discussed in detail. The study also presents preventive measures to be taken to prevent similar manufacturing defects and possible directions for future research.
