SUBSTANCE: proposed method comprises two stages of machining, at least, one 3D microstructure by cutting to remove functional layer of said microstructure. At first stage, cutting is made by high-speed milling. Note here that conical milling cutter is used to remove main part of functional layer material with allowance for finishing retained. At second stage, machined surface is subjected to single or twofold indenting. Note that functional layer material is removed with the help of polyhedral, primarily, trihedral pyramidal cutting tool, every side of which making tool front surface, while tool replacement is carried pout automatically. Said finishing is made in one pass along the microstructure contour by planning at second stage. Note here that first and second stages are performed by aforesaid one tool.

EFFECT: better milling performances.

FIELD: metallography, possible use for making sub-micron (nanometer) relief structures in functional layers of metallographic forms.

SUBSTANCE: in accordance to invention, method is realized by means of multi-pass processing of functional layer of product by cutting. In places of connection of contour parts of projection being formed with different (relatively to base system of coordinates) angular orientation, bisector grooves are cut in direction towards strippable stock. Then side faces of pattern fragment projection are formed. During that on one of technological transitions contouring of aforementioned projection along perimeter is performed (at least one the side of one of faces being formed) by forming a groove along appropriate projection rib with depth lesser than given height of projection. After that stock remaining between projection elements is removed with creation of its given profile without violation of integrity of section of face formed during contouring. Removal of stock remaining after contouring is performed in two stages. During first stage (equidistantly to the groove made during contouring process) a groove is cut with depth equal to given height of projection. During creation of this groove, cutting edge of tool (defining the projection face) is moved towards strippable stock for value limited by technological processing tolerance, to prevent contact of this cutting edge with section of projection face formed during contouring process. During second stage remaining stock is removed by means of successive passes of tool in zone which is limited by the groove formed during first stage.

EFFECT: increased efficiency.

FIELD: metallography, possible use for forming submicron relief structures in functional layers of metallographic forms.

SUBSTANCE: in accordance to method, by means of at least one technological transition sides 4,5,6,7 of profiled linear groove 8 of pattern fragment 3 are formed by means of shaping of functional layer of product 2. After full profile of groove 8 is formed, in internal corners of mating sections, at least parts of sections of curvilinear contour of groove 8 with different, relatively to base coordinates system, angular orientation, cold-hardening is removed which appeared during plastic deformation of material of functional layer during forming of profiled contour of groove 8. For that purpose in bisector area of aforementioned mating sections cuts 10 are made, directed towards area of groove 8 adjacent to bottom with exit of cutting part of tool onto upper plane of functional layer of product 2. Cuts 10 are made by shaping with length not exceeding size of side 4 or 5 of profile of groove 8 in direction of cut 10 in place where aforementioned cut 10 is made. Cut 10 is, as a rule, made during one pass of tool.

SUBSTANCE: in implementing the method, the selective ablation of the masking layer is carried out to create on the masking layer on the entire image which comprises a fragment of the image containing the cell structure. On the masking layer the oxygen barrier layer is applied. Then, the printing element is exposed by the actinic radiation through the barrier and the masking layers for selective crosslinking and cure of at least one light-cured layer to create the relief image and a textured surface on the printing element. The performs of the printing element are developed by removing the barrier layer and uncured parts of the light-cured layer to reveal a relief image.
