Friction-stir processing is considered a green manufacturing process of surface composite fabrication and surface modification. Surface integrity includes different parameters such as roughness, topography, microhardness, and chemical analysis, which is one of the primary features of FSP. The goal of this research is to evaluate the surface integrity of FSP on aluminum matrix nanocomposite. The main parameter effects, including rotational speed, pass number, and the traverse speed on the surface roughness, surface topography, microhardness, and chemical analysis, were studied compressively. The obtained result revealed that the model of the quadratic polynomial is fitted to predict surface integrity. Furthermore, the results showed that the pass number and rotation speed 45.7% and 21.2%, respectively, have the most impact on surface roughness. The most impact on hardness belonged to traversing speed with 55%. Such a way, energy-dispersive spectroscopy analysis revealed that in the traverse speed 50 mm/min the microhardness achieve 127.24 Vickers.

Austenitic stainless steel 304L (AISI304L), of varied thickness, is widely used in the fabrication industry and in many cases, it requires contour machining for achieving intricate profiles. Abrasive water jet machine is a proficient alternative for machining difficult-to-cut, reflective, conductive, and heat-sensitive materials such as austenitic stainless steel with complex geometries. However, due to differences in machining responses for varied material conditions, the abrasive waterjet machine experiences challenges such as kerf geometric inaccuracy and low material removal rate. In this study, an abrasive waterjet machine is employed to perform contour cutting of different profiles to investigate the impacts of traverse speed and material thickness in achieving a lower kerf taper angle and higher material removal rate. Experimental results show that all profiles encountered a similar trend of obtaining higher kerf taper angle and material removal rate as traverse speed increased. Analysis of variance revealed that material thickness denotes a more significant impact to kerf taper angle and material removal rate with a contribution within the range of 69%-91% and 62-69% respectively; whereas traverse speed indicates the least contributing factor within the range of 5%-18% in kerf taper angle and 27%-36% for material removal rate.

“…Despite its many benefits, one the key drawbacks of this technology is that it is not able to achieve the same levels of quality on the machined surface as with other more conventional technologies. In this regard and as mentioned before, the focus of researches has been centered on achieving the optimum surface quality in accordance with the input parameters set for the processing the materials, the separation of materials with a modified structure (9), and also for the turning of superalloys, or surface treatments in general (10).…”

The present paper discusses the impact of the speed of an abrasive water jet cutting process on some surface properties and morphology of the S235JRG1 steel. The values of the cutting speeds used for the analysis were of 100, 150 and 200 mm.min−1 respectively. A contact profile method was used to analyze the surface roughness during the conducted tests. In this study, the observed surface roughness parameters were the Ra, Rt and Rz, respectively. At the same time, these parameters were measured in three positions, i.e.: at the inlet (A), in the middle (B) and at the exit position (C) of the water jet nozzle with respect to the machined material. The experimental study showed that the roughness of the surface reached higher peaks and was more pronounced at the exit position (C) of the water jet. Similarly, it was also concluded that a better quality of the surface was achieved at a speed of 150 mm.min−1.
