“…160 m/min), and increases with increasing depth and feed. The change in the Ra parameter is in the range of about 1 μm (Ra = 1.1÷2.2 μm) [9]. Similar relationships were observed when processing the AZ61 alloy (vc to 200 m/min).…”

The purpose of this investigation was to determine whether and to what extent the technological parameters of turning (feed, cutting speed) affect selected surface roughness parameters of aluminum alloy EN-AW 7075 (AlZn5.5MgCu). The principal findings indicate a significant impact of feed and show on the surface roughness and simultaneously show that cutting speed has no effect on the value of surface roughness parameters under investigation. An artificial neural network was employed to evaluate the prediction of surface roughness parameter Rz in turning.

“…Severe plastic deformation is described for refined and transition layer in near surface region, followed by the bulk material. Lu et al [52] described a stress layer depth in near surface region of AZ31, visible by varying microstructure in contrast to the bulk material. The stress layer depth increased with decreased cutting speed.…”

Mg-xGd alloys show potential to be used for degradable implants. As rare earth containing alloys, they are also of special interest for wrought products. All applications from medical to engineering uses require a low and controlled degradation or corrosion rate without pitting. Impurities from fabrication or machining, like Fe inclusions, encourage pitting, which inhibits uniform material degradation. This work investigates a suitable etching method to remove surface contamination and to understand the influence of etching on surface morphology. Acetic acid (HAc) etching as chemical surface treatment has been used to remove contamination from the surface. Extruded Mg-xGd (x = 2, 5 and 10) discs were etched with 250 g/L HAc solution in a volume of 5 mL or 10 mL for different times. The microstructure in the near surface region was characterized. Surface characterization was done by SEM, EDS, interferometry, and ToF-SIMS (time-of-flight secondary ion mass spectrometry) analysis. Different etching kinetics were observed due to microstructure and the volume of etching solution. Gd rich particles and higher etching temperatures due to smaller etchant volumes promote the formation of pits. Removal of 2–9 µm of material from the surface was sufficient to remove surface Fe contamination and to result in a plain surface morphology.

“…The microhardness mapping profile can be used to indicate the presence of plastic deformation profile across the thickness even though there are some others limitation on this convenient approach where a repetition experimental must have a reliable result. According to Lu et al (Lu et al, 2016), the hardness is high near the machined surface and gradually decreased toward the depth in high speed cutting of AZ31 magnesium alloy. In addition, the high cutting speed produced lower hardness near the machined surface.…”

The chip formation in mechanical machining / cutting process involves thermal loading and mechanical loading in the form of large plastic deformations, high strain, strain rates and high temperatures in the cutting zone. These loadings usually induce plastic deformation in the form of residual stresses in the surface and sub-surface of the machined workpiece. Residual stress issue is essential to be studied in order to control the quality and fatigue life of a component or part produced by machining process. Therefore, the magnitude and depth of the residual stresses into the workpiece sub-surface is important and necessary to be measured. The objective of this paper is to discuss various study on the effects of machining parameters on residual stress and residual stress measurement methods for machined workpiece namely non-destructive, semi-destructive and destructive methods. In addition, the effect of machining process into the metallurgical conditions of the workpiece in the form of microstructural changes is also discussed.
