In this work, the performance of PCBN tools when turning a welded hard-facing material is reported. The chip formation process and tool wear modes were studied and suitable machining parameters were determined by cutting tests. Chipping of the cutting edge and flaking of the rake face were found to be the predominant wear modes of the cutting tools. Finally, the machinability of the hard-facing material and the requirements of the tool material are discussed.
