Study On Chip Investigation and Surface Quality in Vibration-assisted Swing Cutting of Aluminum Silicon Carbide
To gain a comprehensive understanding of the machining mechanism in vibration-assisted swing cutting of aluminum silicon carbide SiCp/Al,a three-dimensional simulation model is established to compare vibration-assisted swing cutting with conventional machining processes of SiCp/Al at different cutting speeds.This research analyzes the damage to the aluminum matrix and particles at various cutting depths and examines the chip morphology.The results indicate that the surface quality of SiCp/Al in vibration-assisted swing cutting is closely related to tool oscillation.The presence of cutting forces,frictional forces,and feed force reversal phenomena promotes plastic deformation of the aluminum matrix and partial fracture of particles,reducing particle damage.However,this effect gradually diminishes with increasing cutting speed.Com-pared to traditional turning,chips produced during vibration-assisted swing cutting exhibit an S-shaped morphology and are more prone to fragmentation.This study contributes to the further enhancement of technology related to vibration-assisted swing cutting for challenging-to-machine composite materials.
