Abstract:Although abrasive machining is among the oldest manufacturing principles, it is still essential for today's industry. Abrasive tool quality is significantly affected by the quality of the contained abrasive grits. This paper gives an overview on the most important grit properties for grinding tools with regard to tool performance and manufacture. These properties include grit size, shape, and toughness. Relevant techniques for grit sorting and analysis (sieving, sedimentation, shape sorting, friability testing, etc.) are presented and compared with regard to the controlled grit properties. Grit quality remains an important criterion for tool performance. More transparency in grit sorting techniques and quality indicators for abrasive grits can help many stakeholders: grit producers, tool manufacturers, and tool users. Moreover, recycling of used grinding tools might become a future market.

“…Grinding is traditionally designated as a final machining process, providing superior surface properties to the ground part, such as smoother surfaces and tighter dimensional tolerances (Malkin and Guo, 2008;Winter et al, 2015). These improved surface properties can positively affect the part lifespan and function efficiency (e.g., by friction reduction of the ground part), thereby reducing the negative potential environmental impacts during its usage (Aurich et al, 2013;Kirsch et al, 2014;Linke and Overcash, 2012).…”

Among machining processes, grinding has been used to achieve high dimensional tolerances and surface quality on workpieces. Yet, high levels of energy expenditure per volume of removed material and the need for cutting fluids make grinding one of the most environmentally impactful machining processes. Furthermore, changes in parameters such as grain and bond specifications of the grinding wheel, cutting speed, and specific material removal rate can lead to different productive and environmental results. Thus, the analysis of grinding processes should not be aggregated and leveraged into a single and broad output parameter. Instead, comprehensive study should be performed, in which the most relevant process parameters, inputs and outputs are considered. This paper presents a detailed study of grinding process, including the characterization of machine subunits and production modes, along with the use of a combined life cycle assessment hybrid model and real-time monitoring system to evaluate the consumption of energy, tooling, cutting fluid and compressed air. A detailed cradle-to-gate life cycle assessment study using eleven different impact categories and a productive performance assessment were performed to evaluate the effects on varying specific material removal rate and wheel type. For equal values of specific material removal rate, the change from a conventional wheel to a cubic boron nitride represented a power requirement increase of 19–24%. Cubic boron nitride wheel achieved remarkably better results on the wheel wear and part roughness indicators for all tested conditions. The environmental performance assessment showed a strict relation between the process environmental impacts and the consumption of electric energy and cutting fluid. To conclude, despite the higher power requirements, the combination of cubic boron nitride wheel with high values of specific material removal rate optimizes both the productive and the environmental results

“…However, the wheel wear during grinding is relatively high, which leads to frequent truing of the grinding wheel. Study [4] deals with an assessment of the embodied energy of a common corundum grinding wheel and a coated cemented carbide end mill. It was found that higher sustainability is achieved by using the grinding wheel rather than the end mill, despite a much higher embodied energy.…”

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.
