摘　　要：阐述国内外现行的数控机床切削负荷检验方法,介绍现有标准中切削负荷试验的检测内容和流程。以三轴立式加工中心为测试对象,分别进行了机床主传动系统最大扭矩切削、最大功率切削等检测试验。通过机床在最大扭矩、最大功率时对应的材料去除率,评估机床重切削能力。最后,对试验结果进行了分析,并在此基础上探讨了切削负荷试验在机床设计中的应用。A system elaboration on the current machining centre cutting loading test method of home and abroad has been carried out, content and process of cutting loading test in the existing standard is presented. Use the 3 -axial vertical machining center as a test machine, main drive system cutting test with maximum torque, main drive system cutting test with maximum power have been implemented, respectively. Material removal rate corresponding to maximum torque, maximum power is evaluated, and then heavy cutting ability of the machine tool is evaluated. Finally, the measured results are analyzed, and on this basis, application of cutting test in machine tool design has been discussed.
