Proposed is a method of machining and a tool (1) to be used for obtaining patterns (4) in the form of alternating ridges (12), pads, cells and ridges of triangular cross section on the surface of a blank (15). The method proposed facilitates selection of the geometrical parameters of the tool (1) and the machining mode to obtain projections (12) at predetermined intervals and of predetermined height and angle of slope. The width of the spaces between projections can be varied between units of millimetres and units of micrometres. The method produces no waste and is highly efficient, requires only simple equipment and can be used to obtain efficient heat exchanging and evaporating surfaces, produce capillary-porous structures in thermal pipes and fine slit filters, obtain thick composite layers on the surfaces of components, machine threads, or treat surfaces undergoing plasma spraying, glueing, or diffusing welding. The invention can be used in general machine building and in power-generation, chemical, refrigeration and cryogenic engineering. <IMAGE> |
