铝基碳化硅(SiCp/Al)复合材料因其优异的力学及热学性能在航空航天领域有广阔的应用前景,而增强颗粒SiCp 严重影响SiCp/Al复合材料的切削表面质量.利用表面轮廓仪和扫描电镜研究不同铣削参数下SiCp/Al复合材料的加工表面质量及切屑形貌,并建立进给量和铣削速度相关的粗糙度模型.研究结果表明:粗糙度值随进给量和铣削速度的增加而增加;铣削速度是加工表面微观结构特征演化的主导因素,并且凹坑随铣削速度的提高而减少;不同铣削参数下的切屑均为崩碎状,铣削速度越快,切屑尺寸越小.
Effects of Milling Parameters on Surface Quality and Chips of SiCp/Al Composites
Aluminum based silicon carbide(SiCp/Al)composite has a broad application prospect in the field of aer-ospace because of its excellent mechanical and thermal properties.However,the presence of reinforced particle SiCp serious-ly affects the cutting surface quality of SiCp/Al composite.The surface quality and chip morphology of SiCp/Al composites with different milling parameters are studied by using surface profilometer and scanning electron microscope,and the rough-ness model related to feed rate and milling speed is constructed.The results show that the roughness value increased with the increase of feed rate and milling speed.The milling speed is the dominant factor in the evolution of the microstructure characteristics of the machined surface,and the pits are less with the increase of milling speed.In addition,the chips under different milling parameters are crumbling,and the faster the milling speed,the smaller the chip size.
