Investigation of the effect of machinability parameters by voice activated ultrasonic sound wave device during turning process of pre-heated mild steel

Abstract

Surface roughness represents the dimensional accuracy of the finished product and is one of the most important quality requirements of the finished product. Surface roughness is generally detrimental to the efficient performance of machined parts, especially where relative motion between parts is concerned. For improvement of the surface quality several techniques like magnetic field, ultrasonic assisted turning etc has been introduced. Ultrasonically Assisted Turning (UAT) has been one of the techniques which showed great promise. It is a hybrid technique based on superimposition of ultrasonic vibration on a movement of a cutting tool in turning process. A sonotrode is usually used for applying the ultrasound frequency. But this is expensive and difficult. However, the present study investigates a new technique of application of ultrasonic sound waves. Instead of superimposing the ultrasound on the tool movement, ultrasonic sound waves have been applied into the turning cutting process externally. For making it more comfortable ultrasonic sound wave has been applied by voice it works through voice rather than manual controller. It is cost effective and easy to introduce.
