WORKING METHOD Russian patent published in 2001 - IPC

FIELD: machine engineering, namely cutting by means of blade tools with preliminarily strengthening, grinding or intersecting fibbers of composite parts. SUBSTANCE: method comprises steps of cutting by means of blade tool while previously using tool for shaping surface to be cut. In order to reduce manufacturing cycle period, to enhance quality of juvenile surface of part and(or) operational characteristics of blade tool, shaping tool is placed in zone of transition of cutting surface to cut surface of part. Tool for shaping may be in the form of deforming roller whose one cone surface is designed for plastic deformation of cutting surface and whose other surface is designed for strengthening surface of part; or said tool may be in the form of grinding wheel mounted diametrically opposite relative to blade tool in the form of cutter. Grinding wheel may be cone one; its one cone surface is designed for shaping cutting surface and its other surface - for grinding part surface. At working composite part, grinding wheel may be in the form of disc mounted with possibility of intersecting fibers of composite part before cutting said fibbers with cutter. EFFECT: enhanced operational characteristics of blade tool for cutting composite parts. 5 cl, 3 dwg
