INTRODUCTION work extrusion is a widely used manufacturing Surface roughness refers to the texture of a tool's process that shapes materials by forcing them surface, characterized by the presence of through a die to create products with specific irregularities and deviations from the ideal cross-sectional profiles. The efficiency and quality smoothness. These surface features can of this process are influenced by various factors, significantly impact the interaction between the among which the surface roughness of extrusion tool and the material being extruded. Higher tools plays a critical role. Tool surface roughness surface roughness can lead to increased friction affects not only the material flow but also the final and resistance during extrusion, resulting in properties of the extruded product, making it a key greater force requirements, reduced material flow, consideration in optimizing extrusion and potentially compromised surface quality of the performance. extrudate. Conversely, smoother surfaces may facilitate better material flow and improved https://www.theamericanjournals.com/index.php/tajas 6 THE USA JOURNALS THE AMERICAN JOURNAL OF APPLIED SCIENCES (ISSN – 2689-0992) VOLUME 06 ISSUE08 product finish, but may also influence tool wear practices for tool preparation and maintenance. and longevity. The results are expected to inform strategies for improving extrusion performance and extending tool life, benefiting industries that rely on precision This study aims to investigate the effects of tool and quality in cold work extrusion applications. surface roughness on the dynamics of cold work
