Optimal Selection Process Parameters of Ultrasonic Machining of Tool Stepped Horn Modelling Using FEM Analysis
Journal Title: JOURNAL OF ADVANCED RESEARCH IN PRODUCTION AND INDUSTRIAL ENGINEERING - Year 2017, Vol 4, Issue 1
Abstract
The objective of this study is to investigate the von- mises stresses and total mechanical stress induced in ultrasonic machining tool. Generally, the sonotrodes are made up of metals which have very low acoustic losses and high fatigue strength. The design of stepped horn in terms of resonant frequency and determination of the correct sonotrodes resonant wavelength has been done with their area and diameter ratio. In Harmonic analysis, we find the degree of freedom of solution (displacement vector sum) in stepped Horn. An ultrasonic vibratory tool has been designed and analyzed using Harmonic analysis for calculation of its equivalent (von-Mises) stresses under its natural frequency and working amplitude of vibration. The Harmonic analysis of tool will enable us to find (using ANSYS Mechanical APDL) the nodal displacement with total mechanical strain and deformations values in z direction if get less value deformations then value of deformations also less on the workpiece also. So surface finishing will be more and less tool wear rate.
