Paper Abstract

The pressure distribution is the most vital to material removal in continuous polishing in which removes the scratches and subsurface damage induced in grinding and lapping. Firstly, the interface response mechanism of the static contact pair is determined by uniaxial compression test. Then, the numerical model of the optics (Φ50mm×5mm ) and polishing lap(Φ80mm×7mm) contact pair is established to acquire the pressure distribution based on elastic contact mechanics. After that,the compression behavior is characterized by the pressure distribution and real contact area (RCA) measured by fujing pressure film. Attempt is made to clarify the figure of optics in continuous polishing.
