Study on Chip Morphology of ZA8 Zinc Alloy Composite Reinforced by 316L Network Structure
In order to investigate the chip morphology of network-reinforced composites to clarify their cutting mecha-nisms,cutting tests and cutting simulations are conducted on 316L stainless steel network-reinforced ZA8 zinc alloy compos-ites and ZA8 zinc alloy in this paper.The similarities and differences of chip morphology between the composites and ZA8 are analyzed,and the changes of chip morphology of the composites under different cutting parameters and different rein-forcement pore diameters are discussed.The results show that the chip length and structural integrity of the composites are significantly lower than that of ZA8,and the experimental results are similar to the simulation results.With the increase of cutting speed and cutting depth,the composite chips are more likely to appear striped fragmentation and collapse,while the effect of feed speed is opposite.In addition,the smaller pore size of the composite reinforcement is,the shorter chip length and the more chip fragmentation defects is.
