55%体积分数SiCp/Al复合材料超声辅助磨削实验研究
An Experimental Study on Ultrasonic-assisted Grinding 55%Volume Fraction SiCp/Al Composites
摘要
Abstract
To address the issues of SiC particle detachment and fracture during the processing of SiCp/Al composites,which result in poor surface quality and high cutting forces,SiCp/Al composites with a volume fraction of 55%is investigated.By integrating the kinematics of face grinding and the coupling mechanism of ultrasonic vibration intermittent cutting effects,theoretical analyses and ultrasonic-assisted grinding experiments are conducted to explore the influence of ultrasonic vibration effects,spindle speed,feed rate,and cutting depth on cutting forces and surface roughness.The findings reveal that with the increase of spindle speed,the surface roughness shows a downward trend.As the feed rate increases,the surface roughness shows a gradual upward trend.In addition,when the cutting depth is relatively shallow,SiC particles are prone to breakage,thereby leading to a decrease in surface roughness.When cutting depth is large,surface roughness decreases with increase of cutting depth.Compared to non-ultrasonic face grinding,ultrasonic-assisted face grinding significantly reduces surface roughness,with a maximum reduction of 30.7%.The cutting force decreases as the spindle speed rises,while it increases with the growth of cutting depth and feed rate.Spindle speed and cutting depth have a greater impact on cutting force.Ultrasonic-assisted face grinding also significantly reduces cutting forces,with a maximum reduction of 22.3%compared to non-ultrasonic face grinding.关键词
