Abstract

As a critical finishing process in precision manufacturing, grinding plays a vital role in achieving high dimensional accuracy, yet its performance is severely bottlenecked by intense inherent heat generation that leads to productivity losses and thermal damage. To address these limitations, textured grinding wheels offer significant inherent advantages over conventional wheels regarding grinding force reduction and process temperature management. However, existing literature and predictive models are generally tailored for conventional grinding wheels, failing to capture the highly dynamic, intermittent contact nature of textured surfaces. To address this gap, this thesis presents a comprehensive multi-physics modeling framework designed to simulate the distinct physics of the textured grinding process, specifically developing predictive models for grinding forces and process temperatures. In parallel with model development, the physical production of specialized textured grinding wheels was carried out using active metal vacuum brazing and laser processing. The developed force and temperature models were subjected to robust experimental validation using the manufactured prototypes. The validation results demonstrate the predictive accuracy of the framework, showing that texturing effectively minimizes peak grinding temperatures and forces, thereby improving process efficiency by suppressing the ploughing force. Ultimately, this multi-physics modeling framework serves as the essential foundation and key component required for optimizing both the texture geometry and the overall grinding process parameters to achieve high-performance manufacturing.
