在高速切削塑性金属时,灼热而锋利的带状切屑会沿着前刀面逸出而到处流窜,不仅妨碍切削加工的正常进行,还会影响产品质量和劳动生产率的提高。因此,必须采取适当措施,使其合理折断。评定断屑质量的标准应该是: 1.断层的有效性——切削时应能形成向刀具后刀面和工件待加工表面方向连续排出的环状、半环状和短螺旋状,无害于安全生产并便于清除、运输的切层。 2.断层的广泛性——在较大的切削用量范围内,应能对不同的钢材进行车削加工,具有相应的断屑能
In the high-speed cutting of plastic metal, the hot and sharp ribbon chips will escape along the rake face and run around, not only hinder the normal machining, but also affect product quality and labor productivity. Therefore, appropriate measures must be taken to make it reasonable. The criteria for assessing chip quality should be: 1. The effectiveness of the fault - the cutting should be able to form the direction of the knife to be machined and the workpiece surface to be processed continuously discharged annular, semi-circular and short spiral, harmless Safe production and easy to clear, transport layering. 2. The wide range of faults - in the context of a larger amount of cutting, should be able to different steel turning, with the corresponding chip breaking energy
