This paper deals with the influence of number of hob threads and hob feed on the behavior of crater wear on tool face, flank wear and finished surface roughness using different three kinds of high -speed steel hob materials coated with (Al, Ti) N in dry hobbing. Experiments were carried out using a fly tool. It was found that with all of the hob materials tested, the crater wear decreases with increasing in number of threads and in hob feed, that is, the condition of 3-thread hob and hob feed of 3.0 mm/rev is useful for decreasing the crater wear in dry hobbing. It was suggested that the reason why the reduction of the crater wear under the condition is affected by the adhesion on the tool face. The flank wear showed almost the same tendency as the crater wear and it decreases under the condition of 3-thread hob and hob feed of 3.0 mm/rev. The surface finish is small under the condition of multiple-thread hob and high hob feed.
