“…Figure 8 shows the R a , R z and R t roughness values obtained after conventional turning for 14M, 28M, 47M and 56M samples, respectively. As expected, the results indicate that surface roughness parameters increased due to increasing feed rate, this is because increasing the feed rate leads to a larger separation between consecutive positions of the cutting insert causing a greater distance between peaks and valleys [23,24]. An increase of the feed rate from 0.0356 mm/rev to 0.1422 mm/rev caused that R a , R z and R t roughness parameters increasing by 44.4%, 37.9% and 42.7%, respectively.…”

This study investigates the corrosion potential of ASTM A-36 steel after slide burnishing using different applied forces. Turned samples of ASTM A-36 steel were subjected to slide burnishing surface treatment. The burnishing process was carried out with forces of 150 N, 300 N, and 450 N, at a travel speed of 100 mm/min. The effects of burnishing on the chemical composition of the material were analyzed using Grazing Incidence X-ray Diffraction and X-ray photoelectron spectroscopy, which indicated no changes in the chemical composition of the material. Corrosion potential measurements were performed using the Tafel test. The results showed that as the burnishing force increased, the corrosion potential shifted to lower values. Additionally, roughness analysis suggested that the change in corrosion potential was attributed to plastic deformation caused by the burnishing process. The increased mechanical work exerted on the material during burnishing may be the underlying reason for the observed shift towards lower corrosion potentials with higher applied forces.

“…This may be attributed to the fact that higher cutting speeds produce higher temperatures because the material taking away is more aggressive. As a result, this softens the materials that improve the cutting process and consequently diminish surface roughness [17]. Moreover, when the cutting speed is low, a subsurface material fracture occurs, which contributes to increasing the surface roughness; by raising the cutting speed this effect disappears.…”

Al-based automotive alloys with different level of Si content has been conducted on the characterization of machined surfaces in terms of roughness, temperature, chips formation as well as microstructue evaluation under different machining conditions. For this experiment a shaper machine with HSS single point V-shaped cutting tool is used at different cutting speed and depth of cut. The experimental results show that the surface roughness of the alloys decresess with cutting speed and depth of cut but it is more prominent on cutting speed. It is because of high cutting speed is more associated with the higher cutting temperatur and softening the work material leading to better surface finish. Higher Si added alloys shows the better surface finish due to formation of different intermettalics as more brittle. For brittle and higher hardness it produces the higher temperature during machining. During machining relatively curly and short chips are form by the high Si added alloy becase of its low elongation properties. Fracture surfaces of higher Si added alloy display more crack propagation obtained by the plate-like Si rich intermetallics.

“…Increase in depth of cut causes higher thrust force and leads to higher deformation of the chips. These deformed chips exerts higher pressure against the machined surface and deteriorates the surface finish [24]. The surface roughness decreases from 6.8 to 4.4 μm with an increase in nose radius from 0.4 to 1.2 mm.…”

Enhancing the machining efficiency of hardened steel using four‐layer coated tungsten carbide tools has gained a lot of interest among manufacturing engineers. This paper reports the machining performance of AISI 4140 steel using TiN/Al2O3/TiCN/TiOCN multilayer coated tungsten carbide tool inserts. The impact of cutting speed, depth of cut, and the nose radius on machining force, tool chip interface temperature, surface roughness, and chip forms was ascertained using full factorial machining experiments and artificial neural network (ANN) methodology. The machining force evaluated using Logistic Sigmoid activation function resulted in the highest root mean square error (RMSE) of 4.076 and regression value of 0.998. The maximum error between the ANN predicted results and experimental results for machining force, cutting temperature and surface roughness was about 2.4%, 5.3%, and 2.07%, respectively. The best architecture for ANN was “3‐6‐4” which had a coefficient of regression value of 0.97. However, in case of chip form, some of the ANN predicted values could not be mapped to ISO standard chip form and hence prediction accuracy of 80% was achieved.
