The method for estimation of free-form surface accuracy is described in the paper. The surfaces were scanned by coordinate measuring machine and it implicates the fact that the surfaces are described by irregular nets of nodes and the measuring result requires the correction of the probe radius. The presented method is bases on the comparison of two sets of points which are described by irregular...
The paper presents the problem of the influence of the structure of oxide layers obtained in an electrolytic process on tribological cooperation with constructional materials. Microhardness and abrasion resistance of oxide layers obtained on aluminium alloys by means of hard anodizing depend mainly on their porosity, morphology, surface roughness and layers' thickness. Utilitarian properties of alumina...
The paper presents results of trade-off studies on the effectiveness of internal cylindrical grinding by the use of grinding wheels made of microcrystalline aluminiumoxid type SC and conventional abrasive material type 99A.
The article presents the results of the research on the influence of the cutting speed vc and feed fon the surface roughness in the course of finishing turning of the graphite carbon sealing with the polycrystalline diamond edge. The following mathematical models of relations were received: Ra = g(vc, f), Rp = g(vc, r), in order to establish optimal machining parameters concerning the surface roughness.
The process of surface roughness formation is complex and dependent on numerous factors. The analysis of the latest reports on the subject shows that mathematical relationships used for determining surface irregularities after turning and milling are not complete or accurate enough and, therefore, need to be corrected. A new generalized mathematical model of roughness formation was developed for surfaces...
