Film Polishing Process Simulation And Experimental Study

Differing from traditional dissociation polishing and cloth base or sand belt polishing, the grinding polishing film is a new-style polishing tool with a macromolecule material mixture of AL2O3, diamond powder and imides smeared onto the base. And its base is made of a macromolecule material, which is water-fast and high-temperature-resistant, and also has some flexibility and intensity. Finish machining or super finish machining surface with grinding polishing film have many merits, such as high efficiency, green and so on. With the high-tech development of modern times, the super finish machining technique for the rigidity and brittleness material with good capability has been a focus of extensive attention. Polishing film has a widely applied foreground in finish machining field of optic instrument, magnetism and electronic component and so on. Setting up a film polishing emulation system, which bases on Internet, has great theoretic and practical significance for choosing a reasonable polishing film according to the machining precision demand.In this article, we use maximal similar estimate and dispersion math to analyze the distributing rule of the grinding grain and appearance on the surface. And we summarize the normal school curve of height expectation and square difference of different grinding grain diameters. Utilizing Net Framework technique, we realize the surface appearance and roughness emulation basing on the Internet. At the same time, comparing the surface appearance and roughness of the actual workpiece with the emulation effect after film polishing machining, the validity of math model is validated.In this article, we choose the rigidity and brittleness materials with different rigidity such as boric silicon glass, silicon piece, tungsten cobalt alloy and other materials as the polished objects. And we choose pure water as the coolant when we do polishing experiment in different polishing speed and with polishing film of different grinding grain granularity and grain type on homemade polishing machine. According to the result gained in the experiment, we analyze the relation between the actual polishing precision and the parameters such as grinding grain granularity, type,...
