Material removal in the optical polishing of hydrophilic polymer materials
The optical polishing of hydrophilic polymer materials is a complex process that requires a comprehensive setting of various operating parameters. Based on a series of experimental investigations and dimensional analysis, this paper presents a simple empirical equation to evaluate material removal in the polishing of optical spherical surfaces of hydrophilic polymer materials. It is shown that the polishing load applied governs the material removal, the relative sliding velocity and the sliding distance between the workpiece and polishing tool surfaces. The equation also offers a good reference for the setting of the polishing variables. # 2000 Elsevier Science S.A. All rights reserved.
A Study for the Mirror Surface Polishing by Using the Ring Shaped Tool
The feasibility of mirror surface polishing by using the ring shaped tool (abbreviated as the RST) is studied. This novel polishing process is expected to apply in the fabrication of precise mold and optics. In order to reduce the tool wear effect, the semi-spherical tool was replaced by the ring shaped tool. The experimental results show that the machining rate is not affected by the tool wear, That is, this new process provides excellent machining repeatability. On the other hand, the mirror surface with Ra 4.4nm was yielded in the lager area polishing.
