Experimental study on single grit grinding of Inconel 718 . By TT Opoz and X Chen. Abstract. This article presents an important investigation of material removal mechanism in grinding utilizing single grit scratch tests. The investigation helps people to understand the abrasive cutting behaviour when the abrasive cutting edge shape alters ...
From Fig 6 it is seen that the specific grinding energy of Inconel 751 superalloy varies from 200 to 2000 J/mm 3 for dry condition. Such a wide variation in specific grinding energy reflected on the severity of process due to thermal influence, owing to heat resistant Inconel and bond dynamics making Inconel 751, a difficult to grinding metal.
The grinding process has been investigated in the machining of Inconel 718 with GC, WA and CBN grinding wheels. The machinability discussed here includes surface roughness, dimensional accuracy, grinding force, grinding-wheel wear and grinding-wheel life.
The present work is an attempt to model the components of specific grinding energy in a pragmatic manner. This work explores the contribution of specific energy constituents such as shearing, primary rubbing, secondary rubbing, and ploughing energy while grinding Inconel 718 (IN-718) superalloy.

The results of this study proved that finish grinding of additively manufactured, nickel-based superalloys, such as Inconel 718, can be successfully employed to achieve a reduction in surface roughness of approximately 94 percent when measured parallel to the grind lines and approximately 34 percent when measured perpendicular to the grind lines.
Since grinding comprises both cutting and sliding, it is necessary to provide a balanced environment of heat extraction and lubrication. Thus it requires a controlled grinding environment such as MQL. The current study is an experimental investigation on the significance of the MQL parameters on grinding performance of Inconel 751.
