Devillez et al., studied dry turning of Inconel 718 by coating an uncoated carbide tool. The results of their study showed that using the coating on carbide tools can make it AG 1879 feasible to eliminate the cutting fluid from the process and cutting forces can be decreased comparing using the uncoated tool with flood mode of cutting fluid. Furthermore, in this state, the tool wear can be controlled in spite of operating in the dry machining condition, and coating of the tool can increase the tool life during turning of Inconel 718 (Devillez et al., 2007).
Pawade et al., investigated surface roughness and cutting forces in high speed machining of Inconel 718. The results revealed endocrine system the radial and feed force components are almost equal and the main cutting force component is two to three times of feed and radial force components. The honed plus chamfered cutting edge was influential in reducing cutting forces. It was noted that specimens showing larger cutting forces generated poor surface finish as well as extensive surface damage (Pawade et al., 2007).
