The influence of the microscopical magnification resulting in different voxel size and shape and of the algorithm on parameters used for the quantification of the surface topography is studied using topographical images obtained by confocal laser scanning microscopy. Fracture surfaces and wire-eroded surfaces of steel were used as samples. The values obtained for the global topometry parameters...

Within the context of 5-axis free-form machining, CAM software offers various ways of toolpath generation, depending on the geometry of the surface to be machined. Therefore, as the manufactured surface quality results from the choice of the machining strategy and machining parameters, the prediction of surface roughness in function of the machining conditions is an important issue in 5-axis ma...

This study investigates various models to represent the gross geometric shape of the Moon. Asymmetric polyaxial geometric modelsnamely three-, fourand six-axial lunar figure are compared and contrasted with the axially symmetric three-axis ellipsoidal model derived from Chang'e 1 and SELENE laser altimetry data. All solutions confirm a hydrostatically stable lunar shape shifted with respect to ...

The aim of the study was to determine if any sphincter-like areas are present in the gastrointestinal tract arteries of domestic cattle, and to establish their morphology and topography. It was achieved by analysing the celiac trunks of seven cows. By the means of a light microscopy evaluation, thickenings in the tunica media of the celiac artery and its primary branches were detected. Having d...

It is a fundamental task to monitor the topography and understand changes of intertidal zone for rational utilization sustainable development. A new method proposed identifying terrain zone, using ICESat-2 data replace large amount on-site observation data, thereby reducing costs improving efficiency. Based on pre-experiments correlation analysis, time phase index, water transparency index susp...

Three-dimensional topography measurement is a focus area of precision machining because it provides detailed information on the functional behavior contacting surfaces. The purpose this study to analyze how process parameters and edge geometry cutting insert influence topographical characteristics hardened 16MnCr5 steel surfaces determine favorable combinations technology parameter values based...
