This paper presented a study of abrasive disintegration in a 400 MPa Abrasive Water Jet (AWJ). Abrasive particle size and distribution play a major role in machining and cutting efficiency of abrasive water jets. Tested garnet abrasive, commonly used in the abrasive water jet treatment, and corundum. It is of scientific interest to observe the disintegration of these particles which have been interactive with uncommonly used abrasive materials. Time impact of abrasive grains on the workpiece is very short and not all the grain in the stream of being able to do the work of cutting, you should expect the possibility of recovering the abrasive treatment. Considerable importance is the increase in cutting capacity crushed grains due to reveal new cutting edges. Based on a feasibility study this paper will present some results on achieved cutting data and shows also wear of the used focusing tube -the main part responsible for the formation of the jet.Keywords: Abrasive; water jet; grain size; recycling.Valoración de la desintegración y reciclaje de los componentes abrasivos en procesos de cortes con agua ResumenEste trabajo presentó un estudio de la desintegración abrasiva en un chorro de agua abrasivo de 400 MPa (AWJ). El tamaño y la distribución de partículas abrasivas juegan un papel importante en el mecanizado y la eficacia de corte de los chorros de agua abrasiva. Abrasivo de granate probado, comúnmente utilizado en el tratamiento con chorro de agua abrasivo y corindón. Es de interés científico observar la desintegración de estas partículas que han sido interactivas con materiales abrasivos poco comunes. El impacto del tiempo de los granos abrasivos en la pieza de trabajo es muy corto y no todo el grano en la corriente de poder hacer el trabajo de corte, debe esperar la posibilidad de recuperar el tratamiento abrasivo. Considerable importancia es el aumento en la capacidad de corte de granos triturados debido a revelar nuevos bordes de corte. Con base en un estudio de factibilidad, este documento presentará algunos resultados sobre los datos de corte obtenidos y muestra también el desgaste del tubo de enfoque utilizado, la principal parte responsable de la formación del chorro.Palabras clave: Abrasivo; chorro de agua; tamaño de grano; reciclaje.

“…They discovered that corundum, which was approximately equal to garnet, increased cutting speed at 20%. Garnet has a comparatively low wear of focusing tubes when utilized [90]. A survey reported that 90% of users employ garnet as an abrasive type during AWJM applications [4].…”

Abrasive water jet machining has been extensively used for cutting various materials. In particular, it has been applied for difficult-to-cut materials, mostly metals, which are used in various manufacturing processes in the fabrication industry. Due to its vast applications, in-depth comprehension of the systems behind its cutting process is required to determine its effective usage. This paper presents a review of the progress in the recent trends regarding abrasive waterjet cutting application to extend the understanding of the significance of cutting process parameters. This review aims to append a substantial understanding of the recent improvement of abrasive waterjet machine process applications, and its future research and development regarding precise cutting operations in metal fabrication sectors. To date, abrasive waterjet fundamental mechanisms, process parameter improvements and optimization reports have all been highlighted. This review can be a relevant reference for future researchers in investigating the precise machining of metallic materials or characteristic developments in the identification of the significant process parameters for achieving better results in abrasive waterjet cutting operations.

In the textile industry, disposing the waste products after dyeing causes a major environmental issue. The mordants used leads to adverse effect for the human and other living organisms. Plasma processing is ecofriendly and it does not produce any waste, pollution free on the environment. Therefore, low temperature plasma treatments are set to make a revolution in textile industry. The present work is to modify the surface of cotton fabric by oxygen plasma treatment with operating parameters such as exposure time, discharge potential and base pressure are kept constant as 5 min, 400V and 9 Pascal respectively. The surface roughness of the fabric is analyzed by laser speckle technique for plasma treated and mordanted fabric and then corresponding results were reported. Further, we observed the increase in surface roughness of the fabric after plasma treatment.
