Abstract Metal matrix composites are catching the eyeballs of various industries because of their enhanced properties like higher strength value over lesser weight, good stiffness and satisfies wide applications throughout. But to bring composite to use, always necessitate some machining process which remain a challenge for its user. In current research work, three Aluminum Metal Matrix composite (AMC) have been prepared by stir casting technique-AMC with eggshell (6% wt, 104 μm), AMC with boron carbide (6%wt, 104 μm) and hybrid AMC(6%wt egg shell+6%wt B4C, 104 μm). After preparation of composites, CNC turning is conducted at fixed process parameters of cutting speed 500 rpm, feed rate 0.1 mm/rev and depth of cut 0.5 mm. After the experiments, the responses such as material removal rate (MRR), surface roughness, residual stress and temperature between tool-work piece interfaces are recorded and evaluated. The experimental study revealed that MRR of hybrid and eggshell AMC's are found 43.24% more than the base alloy. It has also been observed that minimum surface roughness (Ra) of 2.2252 μm has been recorded for hybrid AMC. Base alloy shows the highest value of residual stress both, normal residual stress with value equal to (−) 48.5 MPa as well as shear residual stress with value (+)20.5 MPa whereas maximum average temperature of 51.1 °C recorded for hybrid composite among all the AMC's and base alloy.

CNC车削过程中不同增强材料对铝基复合材料各参数的影响

摘要 金属基复合材料因其强度高、重量轻、刚度好、应用广泛等优点而受到各行各业的关注。但是要使用复合材料，总是需要一些加工过程，这对其用户来说仍然是一个挑战。在目前的研究工作中，已经通过搅拌铸造技术制备了三种铝金属基复合材料（AMC）——蛋壳型 AMC（6% wt, 104 μm）、碳化硼 AMC（6%wt, 104 μm）和混合型 AMC（6 %wt 蛋壳 + 6%wt B4C，104 μm）。复合材料制备完成后，以切削速度500 rpm、进给速度0.1 mm/rev、切深0.5 mm的固定工艺参数进行CNC车削。实验后，响应如材料去除率 (MRR)、表面粗糙度、记录和评估工具-工件界面之间的残余应力和温度。实验研究表明，混合型和蛋壳型 AMC 的 MRR 比基础合金高 43.24%。还观察到混合 AMC 的最小表面粗糙度 (Ra) 为 2.2252 μm。基体合金显示出最高的残余应力值，法向残余应力值等于 (-) 48.5 MPa 以及剪切残余应力值 (+)20.5 MPa 而混合复合材料的最高平均温度为 51.1 °C AMC 和基础合金。已记录混合 AMC 为 2252 μm。基体合金显示出最高的残余应力值，法向残余应力值等于 (-) 48.5 MPa 以及剪切残余应力值 (+)20.5 MPa 而混合复合材料的最高平均温度为 51.1 °C AMC 和基础合金。已记录混合 AMC 为 2252 μm。基体合金显示出最高的残余应力值，法向残余应力值等于 (-) 48.5 MPa 以及剪切残余应力值 (+)20.5 MPa 而混合复合材料的最高平均温度为 51.1 °C AMC 和基础合金。
