Dear Profs/Drs/Researchers This book discusses advances in materials processing, especially recent trends and applications in welding, grinding, and surface treatment processes edited by me and Dr. Anna Rudawska. A description of current trends in and innovative aspects of the grinding technology, grinding applications, and surface treatment processes is presented, including the grinding technological parameters, grinding machining methods, new and improved technologies of grinding, design of tools for grinding, construction and materials of grinding tools, surface treatment using grinding in adhesive technology, surface characterization after grinding, and new trends in grinding applications in various industries and other technical and technological areas. Grinding technology plays an important role in the surface finishing and surface treatment of many components. The purpose of this book is to provide information on the characteristics and applications of grinding technology. This information enables engineers, scientists, and designers to make effective use of grinding technology and surface treatment in the manufacturing process of various construction elements and the effective development of this technique.

🚀 Excited to Announce My Latest Publication! 📄 I'm thrilled to share my latest research on "Thermo-mechanical characterization of pinless friction stir welding in AA6060-T4 thin sheets" that has just been published in the Welding International journal. In this study, we dive into the less explored territory of pinless Friction Stir Welding (FSW), particularly for AA6060-T4 aluminum thin sheets. We examined how different welding parameters affect the mechanical properties and thermal distribution, yielding valuable insights for optimizing weld quality in industrial applications. 🔑 Key Insights: Pinless FSW offers superior weld quality but requires precise control of welding parameters. Higher rotation speeds correlate with lower maximum temperatures. Optimal parameters achieved efficiency coefficients up to 84%. Significant findings in microhardness profiles, particularly in the Thermo-Mechanically Affected Zone (TMAZ).

🛑 We are more than just taps! The latest issue of SME Engineering Magazine features an article on Meyer Tool & Manufacturing Inc. and their use of EMUGE-FRANKEN USA's TiNox-Cut Trochoidal end mills. These end mills provided exceptionally effective metal removal on a large Titanium billet. According to Meyer Tool, "We were amazed at how productive the TiNox-Cut end mill was at removing nearly 91% of the original billet. The tool life far surpassed any other end mill we had tried in titanium by at least 75%." Interested in learning more? ➡ https://lnkd.in/gK44nJHY Kurt Serlovsky Kenny Urban

Thermoplastic composite sandwich panels are not common. Only a few research groups have looked at the manufacturing of these structures. When using welding techniques to assemble these structures, the heat source is typically located outside of the sandwich structure and the skins are heated through their thickness. Here, Romain Georges Martin presents an induction welding technique applied under vaccuum, localizing the heat dissipation at the joining interface.

I am thrilled to announce that our latest research, titled "Effect of a variable electrode force on the LME crack formation during resistance spot welding of 3G AHSS", has been published in "Welding in the World". This work delves into the fascinating and complex phenomenon of Liquid Metal Embrittlement (LME)—a critical issue affecting materials used in various industries, from automotive manufacturing to aerospace. Understanding LME is essential for improving the safety, reliability, and performance of engineering materials under different conditions. In this study, we explore how a decreasing electrode force affects the LME cracking behaviour of a third generation advanced-high-strength-steel during resistance spot welding in a design of experiment (DoE). 📉 With this new approach, the generation of type A, B and C cracks with depths of up to 100% of the sheet thickness was possible. The results serve as a foundation for future investigations of the static and dynamic mechanical joint performance under the influence of different crack types and sizes. I'd like to express my heartfelt gratitude to the colleagues, project partners and students who made this publication possible!

Beneath the surface of modern grinding technology lies a sophisticated interplay of materials science, engineering precision, and operational insight. The apparently straightforward act of grinding is actually a powerful dynamic of grinding, impact and fatigue at the microscopic level. Advanced wear solutions respond to these conditions at every level of the component's structure. The latest generation of grinding plates is an example of this concept. Their composition is a carefully engineered sequence of properties. Each layer, from the core to the hardened exterior, serves a distinct purpose in the plate's performance matrix. This layered design creates an exceptional balance of impact resistance and surface durability. Specialized welding wires further demonstrate this engineering depth. Contrary to the simplistic "harder is better" maxim, advanced metallurgy now produces alloys that skillfully balance hardness and ductility. The result: weld deposits that can bend under load without compromising integrity. This calibrated design leads to components with significantly longer service life under real-life grinding conditions. Manufacturing processes themselves have evolved to match this level of sophistication. Wire production, for instance, demands precise control not only of chemical composition but also of microstructure—factors that influence weld performance. This granular level of control ensures consistent, predictable performance across diverse applications and production batches. This integrated redesign of grinding components takes into account their entire operational lifecycle in industrial environments. The result is a new class of products that don't just withstand wear - they actively mitigate it, extending their functional life. #integratedmaintenance #grindingcomponents #materialsscience #manufacturingprocess
