Joint Research on Mass Finishing with Kanazawa University Presented at the 75th CIRP General Assembly
The results of our joint research on mass finishing with Kanazawa University were presented at the 75th CIRP General Assembly, held in Turin, Italy, from August 23 to 29, 2026.
The CIRP General Assembly is one of the world’s leading international conferences in the field of manufacturing engineering, bringing together prominent researchers and engineers from around the globe to share the latest advances in manufacturing science and technology.
Kanazawa University presented the following research paper based on the results of our collaborative research:
“Mechanistic linkage between media–workpiece interaction and surface topography in gyro finishing with spherical alumina media”
This study investigated how interactions between spherical alumina media and workpieces during gyro finishing affect the resulting surface topography.
In addition, the depth and frequency of indentations generated during the finishing process were statistically analyzed. The results demonstrated the potential to predict changes in surface roughness over processing time, as well as the time required for the finished surface to reach a steady state.
These findings provide a fundamental framework for theoretically explaining and predicting mass finishing results based on media–workpiece contact and impact phenomena. Mass finishing conditions have traditionally been determined largely through empirical knowledge and experience. By developing a deeper understanding of the mechanisms involved, this research is expected to contribute to mass finishing process optimization, improved surface quality, and greater process stability and consistency.
Tipton will continue to advance the theoretical understanding of mass finishing technology through industry–academia collaboration, contributing to further innovation and more reliable surface finishing processes.
