Abstract: In this work, the performance of a PCBN tool when turning a welded hard-facing material is reported in comparison with that of alternative materials, such as whisker-reinforced alumina in field trials. 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.

Keywords: machining; turning; hard-facing materials; PCBN tools; tool wear; iron-based hard-facings; chip formation; machining parameters; cutting tools; machinability; welded hard-facing.
