A curious observation of phenomena occurring during lapping/polishing processes (2019)
Journal Article
Yang, Y., Li, H., Liao, Z., & Axinte, D. (2019). A curious observation of phenomena occurring during lapping/polishing processes. Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 475(2230), Article 20190304. https://doi.org/10.1098/rspa.2019.0304

We demonstrate that the kinematics of the polishing process is more intriguing than an idealized planetary movement as all the previous studies reported. In reality, the workpiece is pseudo-constrained by the planetary carrier and because of this its... Read More about A curious observation of phenomena occurring during lapping/polishing processes.
