摘　　要：在五坐标加工中心上采用硬质合金刀具对氧化锆陶瓷进行了侧铣实验。基于Matlab软件对采集到的切削力信号进行了时域、频域和小波包分析。研究了进给速度、切削宽度、主轴转速的变化对切削力的影响。实验结果表明:切削力随切削宽度的变化而变化,且近似成正比例关系;随进给速度的增加切削力不成比例增大;切削力在主轴转速低于4000r/min前提下随转速的提高略有减小。Side milling experiments of ZrO2 ceramics were conducted with carbide tools on the 5-axis machining center. Acquired cutting force signals were analyzed with Matlab software in time domain and frequency domain through wavlet packet analysis method . The influence of working conditions on the cutting force was studied such as feed speed, cutting width and spindle speed . The result of experiments indicated that the cutting force changed approximately in direct proportion to the cutting width, compared with non -proportional increasement as the feed speed grows, and declined slightly with the improvement of the spindle speed under 4 000 r/min.
