Investigation on Key Removal Characteristics of Fixed Abrasive Diamond Pellets Elasticity Tool

To further explore the practicality of the fixed abrasive diamond pellets (FADPs) elasticity polishing tool (ET) developed by our group in machining of hard and brittle materials, series of experiments were designed and conducted in this study to investigate the stability and the key technologies related to the whole surface polishing of the proposed ET. The experimental results indicate that the stability of the proposed ET is good after long time polishing, with tiny weight lost, sharp abrasives and stable tool removal function. Moreover, due to the composite characteristic of flexibility and stiffness of the ET, by controlling the exceeding distance of ET over workpiece, the warping edge after polishing can be significantly reduced, thus the edge effect in polishing process can be obviously suppressed. In addition to above, along with the increase of the spacing of tool path, the roughness of workpiece surface after polishing increases, while both the total time of a polishing cycle and the removal depth of workpiece decreases. All of the above results prove the practicability of the proposed ET with FADPs. Consequently, in practical polishing, comprehensive optimal polishing quality can be achieved by taking above three factors into account using the proposed ET.
