Abstract: | 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. |
