FIELD: process engineering. ^ SUBSTANCE: invention relates to combine machining of shaped part. Proposed method comprises the following stages. Cutter from conductive material with nonconductive abrasive material is revolved. Electric power is fed to machined part and cutter from power supply. Coolant is circulated there between. Note here that said coolant comprises one or more additives intended for increasing electric discharge between cutter and part. Part is arranged to preset cutting depth relative to cutter to be displaced relative to part for part roughing. In roughing, material is removed at relatively high intensity using high-speed electroerosion. Note here that power source provided first differential potential while coolant circulates at first flow rate and at first pressure. Cutter to be displaced relative to part for part finishing. In finishing, material is removed with relatively low intensity using precision electrolytic grinding. Note here that power source provided second differential potential while coolant circulates at second flow rate and at second pressure. ^ EFFECT: optimised cutting time and part clamping. ^ 17 cl, 5 dwg |
