A high-nickel alloy is well known as a difficult-to-machine material. Tool damage in the cutting of this material is not explained sufficiently although many researches have been done. In order to clarify the tool damage screw thread turning and reveal the mechanism of the tool wear, the high-nickel alloy was turned with the tool of four grades of carbide tools, and the cutting forces and the tool wear were investigated. Moreover, the cutting temperature was measured. The main results obtained are as follows : In screw thread turning of high-nickel alloy, the groove wear on the flank was formed. This qroove wear was also observed in outer turning. The flank groove wear almost grew larger than the boundary wear. This flank wear seems to be caused by the softening of the tool materials and the diffusion arising from the cutting temperature.
