what is tungsten carbide. Cemented carbide consists of hard phase such as WC TiC TaC VC and Cr3Cr2 and metal binding phase such as Co Ni and Fe etc It combines the high hardness and good wear resistance of carbide phase and sufficient mechanical property and heat shock resistance of metal binding phase and has been widely used in many aspects.
The cemented carbide tool offers the best performance at a cutting speed of v c = 195 m/min and the ceramic tool at v c = 390 m/min. With these parameters (Table 4 ), a material removal volume of V W = 18,000 mm 3 was machined (material removal rate Q W = 4,032 mm 3 /min). All experiments were repeated three times.
