摘　　要：在金属切削过程中,采用三维复杂断屑槽断屑是实现切屑控制的有效手段之一.在切削试验的基础上提出了三维复杂断屑槽型的切屑折断界限曲线;分析了非直槽型、凸曲面槽型对切屑的约束作用,建立了切屑折断界限的数学模型;为验证切屑折断界限数学模型进行了钢外圆车削的断屑试验.试验结果证明切屑折断界限数学模型是合理的.Chip breaking using 3-D complicated groove insert is one of effective methods for chip controlling in metal cutting process. According to experiments, there are chip-breaking limits in machining chip-breaking chart, which determine the chip-breaking range. Based on analyzing the chip subject to 3-D complicated grooves, the models of chip breaking limits are established. In order to verify the models, chip breaking experiments are performed and the results show the chip breaking limits＇ models are reasonable.
