ethod for making relief in functional layer of printing form // 2299813
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.13 cl, 3 dwg

Impression pattern forming method in functional layer of article by multi-pass planing in nc machine tools and planing cutter for performing the same // 2296036
FIELD: micro- and(or) nano-technology.SUBSTANCE: method comprises steps of removing allowance in central zone of working during rough pass and then finishing surfaces of lateral faces of shaped fragments of pattern along the whole depth of rough working pass. It is realized at using only one lateral edge of cutter to be rotated around its lengthwise axis in curvilinear and broken portions of its cutting path while providing optimal three-dimension position of front surface of cutter relative to cutting surface. Rough passes are performed by means of cutter while using in first pass simultaneously two lateral cutting edges and then using only one of said cutting edges turned to formed lateral face of shaped fragment of pattern. In order to enhance accuracy and quality of working by providing possibility of removing allowance in zones of pattern with broken cutting path during process of removing allowance remained after rough working at finishing, in zones of internal angles of broken portion of cutting path and in zone of portions with small joining radius cutter is lifted for providing outlet of its working part onto upper plane of functional layer of article. Then cutter is turned by angle normalized by cutting path going-on line and it is again fed-in to allowance portion remained after lifting cutter by initial depth. Cutter is lifted and descended while simultaneously imparting to it main cutting motion into zone of removed allowance. Planing cutter includes stem and working part restricted by flat front surface with lateral cutting edges and profiled back surface with lead angle equal to zero for forming end portion of working part. Cross section of working portion is in the form of axially symmetrical figure. Generatrices of back surface are inclined by the same angles relative to axis of cutter stem. End portion of working part is flat one and it is the form of oval-half whose plane is spatially inclined by acute angle relative to front surface. Rib formed by crossing of end portion and front surface serves functionally as third cutting edge; it is oriented by angle 90° relative to lengthwise axis of cutter.EFFECT: improved accuracy and quality of planing by such cutter.7 cl, 20 dwg

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.
