“…Schornik V. [6] confirmed in a practical experiment that the chemical composition and the thickness of the thin layer influences the durability and cutting forces when milling nickel alloy Inconel 718. Therefore, it is important to pay attention to the choice of the proper thin layer for machining Inconel 718.…”

Currently one of the most important tasks of industrial enterprises is fulfilling the required quality of the products. This article is focused just on surface roughness, because product quality is an extensive concept. To obtain the desired product shape and dimensions, a cutting tool must remove the necessary volume of chips. The cutting tool and process conditions also affect the surface roughness during the machining process. The effect of the cutting edge radius on the roughness is studied during the experiment. The cutting tools have modified microgeometries. There are six cutting tools with cutting edge radii of 15 μm; 20 μm and 25 μm. The roughness measurement was performed using the non-contact method on an IGM G4.

This article deals with testing cemented carbide cutting tools during the experimental cutting of Inconel 718 super-alloy. Several carbide end-mills with different cutting edge qualities obtained by different grinding conditions and strategies were used for machining Inconel 718. The main aim is to compare all end-mills in terms of their cutting tool life during cutting. The machining was performed with cutting tools right after grinding without any coating or cutting edge preparation. Cutting forces were measured during machining to find out the influence of the cutting edge quality on the cutting force Fy during the first impact of the tool. Cutting force at the end of the tool life was also measured. The strategy of side milling was used for the cutting tests of tools during machining of Inconel 718. This material is used for highly stressed components in the nuclear industry, such as combustion turbines. The material is very problematic for machining due to its rapid hardening and high heat generation. The influence of the cutting edge after grinding on the cutting process is assessed by means of flank wear and cutting force.

“…Carbide cutting tools are widely used for machining Inconel 718 in the form of solid cutting tools or cutting inserts. Several studies [1,2] deal with the lengthening of the cutting tool life by modification of the cutting edge. It was found that using an optimal value of the edge radius is important for good adhesion of the thin layer and longer tool life.…”

This article deals with the experimental grinding of Inconel 718. This material is used for highly stressed components in the nuclear industry, such as combustion turbines. The material is very problematic for machining due to its rapid hardening and high heat generation. Two types of Inconel 718 in the form of testing bars were finished by cylindrical grinding using different cutting conditions and strategies. The main aim is to determine the impact of grinding conditions on the surface quality in terms of surface roughness after grinding. The resulting surface was scanned using an opticalscanning device to observe the topography of the ground surface. The grinding wheel was measured after grinding each bar to observe the wheel wear and the changes of the grinding wheel shape. The spindle load was monitored during grinding to see the effect of different strategies on the grinding process. The results from this work will be used in further studies and contribute to a better understanding of grinding Inconel 718.
