Abstract:

In order to better understand the material removal mechanism during bonnet polishing process, an experimental study on revealing how the key parameters affect the material removal of workpiece from the view of force and friction is presented. Firstly, we propose a setup for the measurement of the polishing forces and the calculation method for the friction coefficient. Subsequently, based on series of experiments, the correlation of key parameters, polishing forces/friction coefficient, and material removal of the workpiece is investigated. It indicates that the variation of the spot size rarely affects the friction coefficient but has evident effect on the normal force, which results in the change of the tangential force (i.e., frictional force) and the material removal. The increase of tool rotational speed slightly affects the normal force, but greatly reduces the friction coefficient due to the friction state, therefore decreases the tangential force, but the material removal still grows because the removal frequency of the polishing tool increases with a larger magnate. The tool inner pressure has little effect on the polishing forces, friction coefficient, and the material removal. The tool surface condition is demonstrated to have great impact on both the polishing forces and the friction coefficient, therefore affects the material removal. Moreover, it is found that conditioning of the tool surface is an effective way to improve the tool removal characteristic. Finally, based on the above results, some suggestions for the optimization of the polishing process are proposed. All the findings in this study are important bases to our future study.
