“…The surface roughness increases with the increase of the traverse speed. This variation is in accordance with all other previous researches done by others [5][6][7][8][9][10]. But the intensity of variation is different.…”

“…Like all previous researches have demonstrated [4][5][8][9][10], the main process parameters which affect the quality of the parts are the jet pressure, the traverse speed and the abrasive flow rate. Because the jet pressure is recommended to be used at the maximum value provided by the equipment for productivity reasons this parameters was kept constant.…”

“…Some manufactured parts can be seen in Figure 2b. The main parameters of influence which are considered by the comprehensive researches until present day [3][4][5][6][7][8][9] are the water pressure, the traverse speed, the abrasive flow rate and the standoff distance between the nozzle and the surface of the material to be cut. As the water pressure directly influences the process productivity and costs, almost all researches agree that it is better to use the maximum values given by the equipment.…”

Abstract.One of the main present industry challenges is finding the most efficient manufacturing process for a certain part. When parts are made of strong steels like Hardox, their fabrication method is usually difficult. Abrasive waterjet cutting (AWJ) is one of the cutting processes which can be used in this case. This paper presents an experimental research on the machinability of Hardox steel by AWJ. The experiments were conducted using a factorial design model considering two of the main influence parameters like the traverse speed and the distance between the nozzle and the surface of the material. Based on the measurement of the dimensions and the roughness of the parts, the influence of the parameters was revealed and analyzed. The manufacturing time was also compared, as it directly influences the production cost. Further research is considered to develop a mathematical model which can be used for a proper choice of the process parameters depending on the initial requirements.

“…In recent years non-conventional cutting methods such as wire eroding, waterjet and laser cutting have become popular for cutting composites due to advantages such as flexibility to cut in any direction, low cutting forces and decent cutting speeds [1,2]. The absence of tool wear makes these methods also attractive for cutting ceramic composites.…”

Abstract. Ceramic matrix composites ("CMC") with a strong fibre-matrix interface can be made damage-tolerant by introducing a highly porous matrix. Such composites typically have only a low interlaminar shear strength, which can potentially promote damage when preparing specimens or components by cutting. In order to investigate the damage induced by different cutting methods, waterjet cutting with and without abrasives, laser-cutting, wire eroding and cutoff grinding were used to cut plates of two different CMCs with a matrix porosity up to 35 vol.-%. For each combination of cutting method and composite, the flexural and interlaminar shear strength of the resulting specimens was determined. Additionally, the integrity of the regions near the cut surfaces was investigated by highresolution x-ray computer tomography. It could be shown that the geometrical quality of the cut is strongly affected by the cutting method employed. Laser cut and waterjet cut specimens showed damage and delaminations near the cut surface leading to a reduced interlaminar shear strength of short bend bars in extreme cases.

“…There are varieties of non-conventional machining processes such as Electric Discharge Machining, Chemical Machining, Laser Machining, AWJ machining, etc., The suitability of machining process depends on material properties and precision of machining. AWJ machining is one of the nontraditional machining method which is generally insensitive to material properties (Folkes, 2009). In abrasive water machining mixture of abrasive such as garnet, silicon carbide, etc., and water is directed on the target material.…”
