Welcome to PSI World Web. This platform is a personal research archive dedicated to exploring the fundamental mechanisms of manufacturing technology that underpin modern precision machining. Drawing from academic training and graduate-level research in grinding processes, this site reflects a long-term effort to revisit, organize, and reinterpret manufacturing science from a mechanism-oriented perspective.
Why We Revisit the Fundamentals of Grinding
In today’s era of AI-driven smart factories and high-energy laser processing, one might ask: Why do we still emphasize grinding models from the 1970s and 80s? The answer is fundamental: The physical laws governing material interaction never change. Whether using a traditional abrasive wheel or a state-of-the-art fiber laser, the mechanism by which a tool interacts with a workpiece—specifically through the stages of Rubbing, Ploughing, and Cutting—remains the absolute key to achieving nanometer-level precision. My mission here is to use these timeless physical principles to analyze, optimize, and innovate the cutting-edge applications of the present and future.
The 30-Post Roadmap: A Technical Journey
Through the “PSI World Web” series, I will share a structured deep dive into:
- The Core Science: A masterclass on material removal mechanisms in grinding.
- Modern Applications: Bridging abrasive theories with semiconductor wafer processing and advanced ceramic machining.
- Technological Reviews: A mechanical engineer’s critical perspective on Hybrid Machining, Laser Processing, and Water-jet technologies.
This archive is created for the global community of engineers, researchers, and students who believe that “The basics are the strongest tools.” I invite you to join me on this technical journey toward the pinnacle of precision.
