Prelimenary Investigation of Parametric Optimization on Turning Process Using UVAT Tool Holder Based on Taguchi Method

Abstract

Abstract. Determining of cutting parameters on cutting forces and cutting temperatures is critical during the turning operation. Most of the research is focused on cutting using special toolholder for conventional turning. In this study, the main objective is to study effect of cutting speed, feed rate and depth of cut on cutting force and cutting temperature of alumunium alloy (Al6061-T6) in turning operation. Two different design of UVAT toolholders (D1 and D2) were conducted. Experiments have been applied using Taguchi's experimental design technique. An orthogonal array, signal to noise ratio, and analysis of variance are employed to investigate cutting characteristics of each design. Experimental results show that cutting speed is the most significant machining parameter on cutting forces and cutting temperatures. Continously were followed by feed rate and depth of cut. The lowest cutting force and cutting temperature were obtained when the setting of cutting parameters are cutting speed is 50 m/min, feed rate is 0.05 mm/nin and depth of cut is 0.25 mm.

Damping Impact on 1-Dimensional Ultrasonic Vibration-Assisted Turning Machining

“…UVAT is the next generation of machining in which ultrasonic vibration with high frequency around 20 kHz is applied to the cutting tool with the operation of the piezoelectric actuator [29], [30]. Fig.…”
