Analysis of micro-geometric parameters of cut surfaces

The micro-geometrical properties of cutting surfaces can be quite different. The various surface-finishing processes remarkable differ from each other regarding the movements and the used tools. There are some further influential parameters, including the edge formation and the edge geometry of tools, the sharpness and the wear (cutting time) of the edge-part machined the surface.In the present work comparing examinations were performed on surfaces made with various machining processes. The integrity of differing surface micro-geometries was analyzed with the measurements of surface parameters, as well as with the calculation and discussion of statistical features of the results.Results show that the parameters measured on the same surface may differ significantly depending on surface machining and the state of the tools
