Prediction of Microfinishing Effects with the Use of Abrasive Films Utilizing Data Characterizing Their Surface Topography

The publication describes the methodology and results of the studies on stereometric characteristics of the diamond surface of microfinishing films. This methodology is used in different treatments of precise finishing of very high smoothness and accuracy. One presented the results of analysis of vertices’ size in parallel plane to the film surface and towards perpendicular plane to it. Moreover, one performed an assessment of the distance between the grains using surface decomposition on Voronoi cell surface. In order to determine the film surface necessary to perform a particular microfinishing operation, one developed an index which is dependent on the overall profile of the film in the form of an envelope of the sum of vertices’ projections above a certain level. Studying the formation of diamond aggregates of abrasive grains and the spaces between them, one can conclude about the machining potential of microfinishing film and determine a recommended speed of the film displacement ensuring maximum utilization of this potential.
