轻质铝合金活塞在高承载区域采用铸铁镶块进行适当的强化，这种材料的加工用单一刀具材料比较困难。本文通过有限元分析，研究了立方氮化硼作为切削刀具切削陶瓷材料的正交切削问题。分析了切削速度、进给量和切削深度等切削参数对切削力和表面粗糙度的影响。将产生最小切削力的参数确定为最小切削力参数，并对这些参数进行了数值模拟和实验研究。机械加工后，金属区域之间的中间结合使用超声波检测进行了研究。双金属加工成功地模拟，其潜力是很容易应用到工业上的重要组成部分。
Light aluminium alloy piston is suitably reinforced at high load-bearing region with cast iron insert, and machining of such bimetallic material is more difficult with a single cutting tool material. Present study focuses on the orthogonal cutting of bimetallic material machining using cubic boron nitride as a cutting tool through finite element analysis. The effects of cutting parameters such as cutting velocity, feed rate and depth of cut on resultant cutting forces and the surface roughness were analysed. Those parameters yielding minimum cutting forces were identified as minimal cutting force parameters, so numerical simulation and experiments were carried out on these parameters. After machining, the intermediate bonding between metallic regions was studied using ultrasonic testing. Bimetallic machining is successfully simulated, and its potential is readily applied to an industrially important component.
