“…The wall finish achieved was because of the mesh size of the abrasives: sufficient hydraulic pressure with fine abrasives will yield a smooth surface comparable to that from grinding. Hlaváč et al 17 used the declination angle for the prediction and control of the AWJ cutting quality. Ramulu and Arola 18 predicted the depth of cut due to cutting and deformation wear for graphite/epoxy composite materials employing regression analysis.…”

Metal matrix composites are difficult to machine in traditional machining methods. Abrasive water jet machining is a state-of-the art technology which enables machining of practically all engineering materials. This article deals with the investigation on optimization of process parameters of abrasive water jet machining of hybrid aluminium 7075 metal matrix composites with 5%, 10% and 15% of TiC and B 4 C (equal amount of each) reinforcement. The kerf characteristics such as kerf top width, kerf angle and surface roughness were studied against the abrasive water jet machining process parameters, namely, water jet pressure, jet traverse speed and standoff distance. Contribution of these parameters on responses was determined by analysis of variance. Regression models were obtained for kerf characteristics. Contribution of traverse speed was found to be more than other parameters in affecting top kerf width. Water jet pressure influenced more in affecting kerf angle and surface finish. The microstructures of machined surfaces were also analysed by scanning electron microscopy. The scanning electron microscopy investigations exposed the plastic deformation cutting of hybrid 7075 aluminium metal matrix composite. X-ray diffraction analysis results proved the non-entrapment of abrasive particle on the machined surface.

“…The cutting walls quality was improved by tilting of the cutting head towards the traverse speed direction to the one-half of calculated declination angle. Declination angles obtained experimentally can describe the material cutting parameters and in perspective even for the determination of some material properties [8].…”

“…The maximum angles al located for the first four quality zones were assigned as 4°, 10°, 18° and 32° respectively. Authors concluded for the prediction and control of the cutting efficiency and quality that the database of materials with applicable characteristics could be easily prepared with the support of these parameters [8].…”

Abrasive water jet machining (AWJM) is one of the most important method used in cutting different types of materials: alloy sheet, marble, glass, rocks. This process is used in the aeronautic, automotive, metallurgy industries and even in some art techniques and textile industry. The method consists in transforming the kinetic energy of a solid particle directed with water jet at a high pressure to remove material through erosion and abrasion. AWJM is low cost equipment compared to other conventional cutting technologies. This paper is an attempt to review the achievements made in AWJM technology for different hardness materials.

“…Softer materials like rubber and foam are cut by pure water jet, abrasive water jets cut harder materials like steel, titanium, hard rock, common or bullet-proof glass, ceramics and even such materials as corundum or carbides. The continuous improvement of the technology includes deeper study of relationships between material properties and cutting quality [5,6] aimed at better understanding of the cutting process as well as prediction and analyses of its results. The basis for theoretical description of the interaction between the jet and material was derived in the or water, solid particles and air), are produced either as slurry jets or injection jets.…”

Objectives:The contribution deals with a risk assessment in practical applications of the high-energy liquid jet technology from the point of view of the risk identification, estimation and evaluation. Materials and Methods: Differences between three different types of workplaces are highlighted and analysed -the indoor, the outdoor and the research ones. Theoretical analyses are supported by particular application of the method for the risk assessment in the Laboratory of Liquid Jets at the VŠB -Technical University of Ostrava. This laboratory is primarily oriented to research. Nevertheless, the conclusions can be used also for predominantly commercial workplaces. Results: Some new considerations and evaluations concerning health and safety are presented. Conclusions: Failure Mode and Effect Analysis (FMEA) procedures were applied and their limitations in risk assessment of water jet-based technologies are explained.
