RELIEF FORMING METHOD IN FUNCTIONAL LAYER OF ARTICLE BY PLANING (VARIANTS) Russian patent published in 2007 - IPC B23D1/00 B41C1/00 

FIELD: working materials by cutting, engraving relief structures.

SUBSTANCE: method comprises steps of removing allowance at least for one pass of planning cutter having stem and cutting part in the form of trihedral pyramid; before starting working and at changing direction of cutting path for opposite one in zone of broken portions of cutting path and in portions of cutting path joined with small curvature radius, rotating cutter around lengthwise symmetry axis of stem by angle normalized by direction of cutting path; in order to improve working efficiency, using cutter with cutting portion in the form of regular truncated pyramid whose lengthwise symmetry axis is matched with lengthwise symmetry axis of stem and whose small base is apex of cutter; using each lateral face of said pyramid depending upon cutting sign as front surface of cutter; at changing cutting direction for opposite and in zone of broken portions of cutting path and also in portions of cutting path with small joining radius, using as front surface of cutter face of cutting part to be turned by minimum angle due to rotation of cutter for optimizing its spatial position relative to cutting surface.

EFFECT: enhanced working efficiency of method.
