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.
