FIELD: metal bending, possibly manufacture of constructional members of aircrafts of hard-to-form materials. SUBSTANCE: method comprises steps of making power frame by bending blank in bending apparatus at using master form with radius of ready frame; bending blank in the form of strip with predetermined cross section by small values along master form; realizing bending along small length by action of bending efforts and efforts of holders in electrothermal field created due to applying electric current to holders. Such method provides strip bending by predetermined radius without stability loss. EFFECT: enhanced operational reliability of power frame. 2 dwg
