抄録

Flank wear characteristics of tungsten carbide tools in turning plain carbon steels without built-up edge have been investigated by measuring temperature, normal stress and wear rate on the flank wear land. It is found that the crater wear characteristic equation, derived from the adhesive type wear model after M. C. Shaw in the previous paper, is able to describe the flank wear as well. However, the characteristic equation of flank wear consists of two characteristic lines with different gradient which intersect at the critical temperature of around 1150 K. It seems that the line in the low temperature side is affected by abrasives in the steels. This abrasion effect could be taken into account by changing the constants involved in the wear characteristic equation. On the other hand, an abrasive type wear equation could be derived so as to have the same expression as our wear equation. Observation of the wear particles by Uehara, however, appears to exclude the possibility of this wear model.
