尽管人们对硬态车削进行了大量的研究，但对间歇硬态车削的研究成果却很少。本文研究了内间歇硬态车削的可行性。首先，切削刀具与不同的立方氮化硼（CBN）的内容进行了评估，根据可加工性：刀具磨损，表面粗糙度，和切削力。在间歇车削的情况下，低CBN含量的刀具比高CBN含量的刀具具有更好的可加工性。对切削损伤层的深度、残余应力的大小和分布进行了评价。实验结果表明，间歇硬态车削可以获得良好的表面完整性，足以取代磨削加工。
Despite the large amount of research on hard turning, there are few results on intermittent hard turning. In this paper, the feasibility of internal intermittent hard turning has been investigated. First, the cutting tools with different cubic boron nitride (CBN) contents were evaluated, based on machineability: tool wear, surface roughness, and cutting forces. In the case of intermittent turning, low CBN content tools had better machineability than high CBN content tools. The depth of the machining damaged layer and the magnitude and distribution of residual stress were evaluated. The experimental results showed that intermittent hard turning can produce surface integrity which is good enough for replacing the grinding process.
