FIELD: process engineering. ^ SUBSTANCE: proposed method is used to machine end mill grooves and comprises positioning of cutting tool relative to billet and forming shaped helical groove in one-pass milling. To decrease the range of tools, end plain milling cutter is used. Note here that milling cutter positioning is performed in arranging it perpendicular to billet so that working face and lengthwise axis are located at preset A and B from billet lengthwise and crosswise axes and turned through process angles and to said axes. Note here that distances A and B may make (0.5-1)R and (0.75-1.5)R respectively, while angle and do not exceed 20, where R is billet radius. ^ EFFECT: higher efficiency of cutting. ^ 2 cl, 2 dwg |
