Abstract
Cutting temperature affects TiAlN tool wear behaviors during machining IN718. However, the effects of Al content on wear behavior and cutting temperature are not clear. In this research, the Ti0.55Al0.45N and Ti0.41Al0.59N tools with the sole variable of Al contents were selected in dry cutting IN718 compared that with uncoated tools. The effects of Al content on TiAlN coating antifriction and thermal barrier effects were mutually analyzed. The tool tribological behaviors were characterized in tool wear initial and terminal stages, respectively. The Ti0.41Al0.59N tools exhibited better antifriction, smaller thermal barrier effect and longer tool life than that uncoated and Ti0.55Al0.45N tool did. The research results could guide for the reasonable selection of TiAlN tools in high-speed dry machining IN 718.
