A technique based on electrochemical etching of metal is suggested for balancing the first four harmonics of nonuniform mass distribution in a metal cylindrical toothless resonator for a cylindrical resonator gyroscope (CRG). An algorithm for removing mass from the resonator surface has been designed with allowance made for analytically calculated angle and depth of the resonator inclined immersion into an electrochemical bath and its rotation about the cylinder axis of symmetry.
