Efficiency analysis using complex ultrasonic vibrations in electroacoustic spraying of axial cutting tools

Abstract

The article considers the electric spark intensification doping methods by using ultrasonic vibrations to obtain the method of electroacoustic deposition. The ultrasonic vibrations use in the deposition process is possible due to the use of an acoustic system at the end of which a naturally swirled waveguide is used. To analyze the waveguide oscillation amplitude dependence on the frequency, the article presents analytically obtained dependences of the longitudinal and torsional components of vibrations. The obtained results reliability of theoretical studies is confirmed by the good convergence of the theoretical and calculated frequency response resonant peaks. The electroacoustic deposition effectiveness method is confirmed by experimental studies of maintaining the hardened drills performance. The experimental data analysis showed a 2-4 fold increase in the total durability period of hardened drills.
