Estimation of a geometrical structure surface in the polishing process of flexible grinding tools with zone differentiation flexibility of a grinding tool

Abstract

In precision processes, the little of cutting layer section causes that the flexible of grinding tools exerts of meaningful influence on efficiency and results of polishing process. The flexible grinding tools with porous flexible bond creates the distinct group of grinding tools from their specific flexible properties. This properties causes that the active surface of grinding tool fitted to shape of working surface in working processes as opposed in grinding grains which are fixed in stiffness bond of grinding wheel. The flexibility of grinding grains decrease the depth of caving grinding grains on working surface and in consequence this process enables small values of roughness parameters of working surface and suitable cutting ability properties of grinding tools. The elastic properties of flexible grinding tools can be modification by zone differentiation the macrogeometry active surface of grinding tool. This modification enables using the small values of roughness parameters as well as suitable optical effects in bright polish. This article presents the results of polishing with the application of the flexible grinding tools of zonal differetation flexibility which was used for the new method of polishing process. In this method direction of lengthwise workpiece feed creates with the plane of grinding wheel a certain angle as well as was perpendicular.
