Experimental Analysis on Ultrasonic Assisted Turning (UAT) Based on Innovated Tool Holder in the Scope of Dry & Wet Machining

Abstract

In the past 17st century, revolution of industrial had been started and transited to new manufacturing processes, going from hand production to machining process. In order to reduce the manufacturing cost and protect the environment, several techniques are used. While lubrication play a significance role in variable parameters, such as tool life, cutting temperature, surface finishing, chip formation and cutting force.In this paper, ultrasonic assisted turning (UAT) was introduced for the machining of Aluminium 6061-T6. In this technique, ultrasonic vibration which excess 20kHz is combine with conventional turning process to achieve combined advantages of both techniques in machining process. UAT control system is developed using function generator to generate required frequency and output voltage direct connected to piezo actuator. While piezoelectric actuator PPA10M is the main device used to convert electrical energy to vibration energy,where the vibration transmitted to the cutting tip and perform in mechanical energy to remove unwanted material and produce precise dimension of work material. The characteristic of this machining process in theoretically capable to reduce tool wear, cutting force and based on current experimental analysis had shown significance improvement on surface finishing and reduction in tool wear. In the present work, comparison data had been done based on conventional and advanced machining process in the scope of wet and dry machining on AL6061-T6.
