摘要
高温合金Inconel 718是一种典型的难加工材料,本文利用DEFORM-3D软件对无涂层、TiC单涂层和TiC/Al_(2)O_(3)复合涂层硬质合金刀具进行钻削高温合金Inconel 718的仿真分析,研究在不同钻削条件下复合涂层刀具的切削性能,并进行钻削实验进行验证。结果表明:TiC/Al_(2)O_(3)复合涂层刀具能有效降低钻削轴向力和钻削温度,其轴向力降低幅度最高为20%,钻削温度最高降低了35%。通过钻削实验验证了仿真模型的准确性,可为实际钻削加工高温镍基合金Inconel 718中选择涂层种类及钻削参数提供参考。
The high-temperature alloy Inconel 718 was a typical difficult-to-machine material.In this paper,DEFORM-3D software was used to carry out the simulation test of drilling high-temperature alloy Inconel 718 with uncoated,TiC single-coated and TiC/Al_(2)O_(3) composite coated carbide tools.The cutting performances of composite coating tools under different drilling conditions were researched and were verified by drilling experiments.The results show that the TiC/Al_(2)O_(3) composite coating tool can effectively reduce the drilling axial force and the drilling temperature,the maximum reduction of the axial force is 20%,and the maximum reduction of the drilling temperature is 35%.The accuracy of the simulation model is verified by drilling experiments,and a certain reference for the selection of coating types and drilling parameters in the actual drilling of high-temperature nickel-based alloy Inconel 718 is provided.
