Nanopolishing processes are used in medical, industrial, telecommunication, optics and military fields. However, rigid tool-based methods, such as diamond turning, grinding and honing, have inherent limitations in creating nanopolished surfaces on hard and profiled surfaces. This study is focused on characterization and modeling of hydrodynamic polishing (HDP) method as a nanopolishing method using aguchi Method. In this process, a film of abrasive suspension is formed between the work-piece surface and a rotating soft-tool which helps in nanopolishing. The past experimental research gives an insight into the process but the process has not been explicitly modeled. Consequently, besides experimental characterization, a numerical mathematical model of hydrodynamic polishing processing is important. Therefore in this work, a model of the HDP process has been proposed, which takes into account the polishing process variables, such as, contact load, spindle speed, tool and work-piece material properties geometry and abrasive suspension properties.
