“…Case-I: Machining with Tungsten carbide inserts and soluble coolant at ambient temperature (30°C): Figure 7 shows the image of the flank and rake surface observed under SEM. There is severe chipping off of the flank surface and abrasion of the workpiece is observed, the reason being heat concentration due to high temperature and sudden impact of mechanical loads resulting in the notching of the fine edge of tools and is the primary reason for the failure [45]. The abrasion of the flank surface is also the result of a built-up edge generated during cutting that slides across the flank surface [46].…”

The work-hardening and low thermal conductivity characteristics of SS304 had always been a challenge to machine it easily with better tool life and surface finish. The type of coolant, its temperature and surface coated inserts plays a pivotal role in machining the hard materials. A number of experiments were performed with a TiCN and tungsten carbide inserts in combination with soluble/synthetic coolant at ambient temperature and at 0 o C TiCN-coated cemented carbide insert with synthetic coolant at 0°C is recommended for machining as per the results obtained through this research work. It was found that TiCN-coated inserts used for machining SS304 with synthetic coolant at 0°C provide better tool life, less tool wear, improved surface finish and low heat generation. The tool life was enhanced approximately by 75%, 20% reduction in maximum temperature generation and 50% improvement in surface finish of workpiece.

“…El uso de un suministro de refrigerante a alta presión puede conducir a una mejora considerable en el rendimiento y el proceso de mecanizado. Debido a la alta presión del chorro de refrigerante, se forma una cuña en la interfaz herramienta-viruta, lo que logra reducir la longitud de contacto herramienta-viruta y el comportamiento de fricción [45]. Además, el chorro de refrigerante es capaz de crear una cuña de refrigerante a alta presión, que se forma entre la herramienta de corte y la viruta para doblarse hacia arriba, lo que mejora el proceso de formación y control de viruta [46], [47].…”

En la actualidad, el interés por usar materiales de desecho y subproductos provenientes del hormigón ha incrementado, debido a la necesidad de minimizar la contaminación en el planeta. El presente documento tiene como objetivo la revisión sistemática de la literatura con respecto a la implementación de los residuos de acero en la mezcla de hormigón, y cómo esto influye en su comportamiento físico-mecánico. Se ha enfocado el interés principalmente en los residuos de acero en forma de escoria, limadura, viruta y fibras, incorporados en todo tipo de hormigón estructural, utilizado en columnas, vigas, zapatas, losas y muros. El uso de estos materiales tiene un alto impacto, pues no solo ayuda a reducir el costo de fabricación de cemento y hormigón, sino que a la vez otorga numerosos beneficios ecológicos, como reducir el costo de los vertederos, ahorrar energía y proteger el medio ambiente de una posible contaminación. Se efectuó la búsqueda de artículos indexados en las diversas bases de datos, tales como ASCE, EBSCO, Google Scholar, ScienceDirect, Scopus y SpringerOpen; se seleccionó finalmente un total de 60 artículos publicados desde el año 2014. Se concluye que el uso de residuos de acero es una alternativa para incorporar a la mezcla de hormigón, pues puede reemplazar parcial o totalmente al agregado y lograr la producción de hormigones que no presenten afección en sus propiedades físico-mecánicas; e incluso, en algunos casos, mejorar dichas características.

In recent years, issues related to eco-friendly machining have received more and more attention, leading to the development of new cooling/lubrication techniques. Herein, the paper investigates the effect of high-pressure coolant (HPC) supply on machining performance of Inconel 718 and compare with conventional flood cooling. Significant improvement in tool life, tool wear, tool-chip contact length, material removal volume, and cutting forces have been observed from the outcomes of HPC cooling condition. Moreover, in order to study the environmental impact of machining Inconel 718, a carbon emissions model was established and analyzed for high-pressure and flood cooling conditions, taking into account the carbon emissions from energy, material, cutting tool, and cooling/lubrication fluid. HPC assisted machining was revealed to be better as it makes possible a reduction in overall carbon emissions at higher cutting speeds. In addition, economic analysis for both cutting environments was also carried out. Significant improvement in reduction of the overall machining cost was observed under HPC conditions, especially at higher cutting speeds. In a nutshell, the findings revealed better performance of HPC assisted machining, with regard to machinability, environmental, and economic issues.
