Abstract

In this study, the amount of WC and group N elements of Ti(C, N) cermet tool was investigated. The composition of WC was changed from 5 to 20% to determine the effect of WC on the cutting performance of cermet tool. The more WC was added, the longer the tool life of the cermet tool was. The cermet with 20% WC showed the best fracture toughness. The effect of group N elements ; ZrC, ZrN and HfC was also investigated by adding each of them to manufacture the cermet tool with fixed 14% WC composition. The cermet with 1% group N ZrC and 14% WC showed the best cutting performance among the investigated cermet tools.
