Effect of SiC particle size and weight percentage on power consumption during turning of AA7075/ SiC composite

Abstract

Power consumption has become a serious issue in current manufacturing for numerous reasons such as, financial savings and environmental protection. The correct calculation of the power consumption for various machining processes remains a challenge. This paper presents an experimental investigation of the power consumption during the turning operation of AA7075/10 wt% SiC (particle size 10–20 μm), AA7075/10 wt% SiC (particle size 20–40 μm), AA7075/15 wt% SiC (particle size 10–20 μm) and AA7075/15 wt.% SiC (particle size 20–40 μm) composite. Machining of the AA7075/ 10 wt% SiC and AA7075/ 15 wt% SiC composites bars was done by using carbide insert CNMG 120404, 08,12EM, grade 6615 at various cutting parameters. Study displays impacts of cutting parameters such as cutting speed, depth of cut, feed rate and nose radius on power consumption during the turning operation of AA7075/SiC composites. Minimum power was consumed during the turning of 04 type of AA7075/SiC composites mentioned in this research, when turning was done at cutting speed of 90 m/min, feed of 0.15 mm/rev, depth of cut of 0.20 mm and nose radius of 0.40 mm. The novelty of this research is that it contributes to the practical features of composite machining knowledge by discovering relations between the effects of SiC particle size and weight percentage on the power consumption, and pertinent power consumption characterisation AA7075/ SiC composites.
