摘　　要：用工业化生产条件下制备的原位TiCp/Fe复合材料,采用PCBN刀具干式切削方法对其机械加工性进行试验.用45#钢与原位TiCp/Fe复合材料进行对比,以说明其可加工性.试验结果表明:原位TiCp/Fe复合材料的切削力比45#钢的切削力要大60N;切削升温比45#钢高出90℃;被加工表面的粗糙度与45#钢相近;原位TiCp/Fe复合材料的可加工性与45#薛钢相似.Machinability of TiCP/Fe in situ composite prepared in industry condition, is experimented by using PCBN tool in drying cutting. TiCP/Fe in situ composite is contrasted with 45# steel to explain machining quality of which. The experiment indicates that the cutting force of TiCP/Fe composite is more than which of 45# steel by 60N, and the cutting temperature of TiCP/Fe in situ composite is higher than which of 45# steel by 90℃, and the roughness of machined surface is almost as much as which of 45# steel. The machining quality of TiCp/Fe in situ composite is similar to that 45# steel.
