Opis:: The carried out research of the processes for the treatment of superfinishing with the application of microfinishing films of IMFF type with heaping the grain from the alundum with the nominal size of 15 micrometers for the different cinematic system proved that the topography of surface after smoothening depends on the cinematic features of process. It is demonstrated that the machining with oscillation can be substituted and the similar effects can be obtained as a result of the deviation from the parallelism of the directions of object feed and foil feed. This means the possibility to apply the super finisher attachments with a simpler building.

Opis:: Superfinishing with the use of diamond lapping films differs to a significant extent from other machining methods. This is finishing surface machining, one which is realized by a slow rewinding of a microfinishing film, putting it in an oscillating motion and pressing the tool to the surface being machined. The surface being machined moves with a speed which is substantially greater than that of the tool feed. A characteristic feature of the process is a one-time use of the tool, the result being a need of an optimal selection of the machining parameters. Investigations of the topography of the microfinishing film surface were conducted with the use of new parameters that describe the arrangement and the shape of the vertices of active grains. The following were used for the purpose of assessment: coefficients that had been developed that describe the features of the shape of the tool surface, such as the standardized coefficient of the flatness of vertices w^N_ki, the standardized number of vertices in relation to an area unit L^N_wi and the dissipation coefficient of the height of the location of vertices w^N_rwi. For the purpose of the assessment of the smoothening ability of diamond lapping films the smoothening potential coefficient w_p was developed, which is defined as the geometric mean of the abovementioned indices.

Opis:: This paper describes the methodology and results of research on the tribological characteristics of the surfaces of diamond abrasive films using a stereometric analysis. Abrasive films are used in various finishing processes of surfaces with very high smoothness and accuracy. A morphological analysis of surface vertexes in the plane that is parallel to the film surface and the perpendicular direction allowed an assessment of the distances between particles by means of a decomposition of the surface into Voronoi cells. When studying the formation of the aggregates of diamond particles and the spaces between them, one may infer about the machining potential of the abrasive film and determine the recommended kinematic conditions of the film that ensures the maximum use of this potential. Owing to the investigations related to the morphology of diamond abrasive films, one can observe relevant characteristic abrasive aggregates that vary in term of size and shape depending on particle sizes. Units with elongated shapes have a superior machining ability in relation to spherical-shaped units. One of significant parameters proposed that describe the technological potential of abrasive films is the edge length to width ratio of diamond units. Different operating modes are discussed. A statistical analysis of the dynamics observed of abrasive interfaces allowed a pertinent description of the abrasive process taking into consideration nominal and apparent as well as abrasively efficient morphologies.
