Influence of Cutting Conditions on the Surface Quality and Grinding Wheel Wear During Cylindrical Grinding of Inconel 718

Abstract

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.

The Influence of Grinding Process and Drag Finishing on the Milling Tools Macro Geometry

“…A certain number of important properties of the tool material such as hardness, strength, temperability and thermal conductivity are required to ensure a long lifetime of cutting tools [11]. There are several publications which investigated the influence of tool geometry on the tool wear [12], [13]. Issue of edge preparation affecting the macro geometrical properties of cutting tools, was not thoroughly investigated, that is why the following research has been carried out.…”

Grinding of Maraging Steel Vaco 180 with SiC Grinding Wheels - Grinding Force and Wheel Wear

“…From this figure it is evident that changing these two parameters can influence the size of wear, grinding forces, the temperature of grinding, cutting time and so on. [2], [3], [4], [5], [6] This paper deals with grinding VACO 180, a material which is used for producing test specimens for mechanical tests. This is because it is equivalent to the material according to DIN X3NiCoMo 18 9 5, but mainly to MS1 steel from EOS, which is used for metal 3D printing.…”

Evaluation of Grinding Wheel Wear when Grinding VACO 180 Steel under Variable Grinding Conditions

“…[2] Of course, the cutting conditions are also affected by other grinding parameters such as forces, temperature, accuracy, roughness and so on which are very important because the grinding is a finishing process from which excellent surface quality and very high accuracy is expected. [3], [4] The aim of this work is to investigate the influence of grinding conditions, especially grinding speed and depth of cut, on the wear of a grinding wheel when grinding maraging steel VACO 180 with two different grinding wheels with SiC abrasive and ceramic binder. The amount of wear on the grinding wheel under different grinding conditions was evaluated.…”
