“…The electric current was measured using a single-phase cable connected to the CNC turning machine's three-phase power supply by employing a clamp meter. The following equation was used to convert the voltage and current to power consumption [42][43][44]. The turning experiments were performed using a two-axis CNC lathe (EMCOMAT-E300, Germany).…”

Electron beam melting (EBM) is one example of a 3D printing technology that has shown great promise and advantages in the fabrication of medical devices such as dental and orthopedic implants. However, these products require high surface quality control to meet the specifications; thus, post-processing, such as with machining processes, is required to improve surface quality. This paper investigates the influence of two-part orientations of Ti6Al4V EBM parts on the CNC machining (turning) process. The two possible EBM part orientations used in this work are across EBM layers (AL) and parallel to the EBM layer (PL). The effect of the EBM Ti6Al4V part orientations is examined on surface roughness, power consumption, chip morphology, tool flank wear, and surface morphology during the dry turning, while using uncoated carbide tools at different feed rates and cutting speeds. The results showed that the AL orientation had better surface quality control and integrity after machining than PL orientation. Using the same turning parameters, the difference between the roughness (Ra) value for AL (0.36 μm) and PL (0.79 μm) orientations is about 54%. Similarly, the power consumption in AL orientation differs by 19% from the power consumption in PL orientation. The chip thickness ratio has a difference of 23% between AL and PL orientations, and the flank wear shows a 40% difference between AL and PL orientations. It is found that, when EBM components are manufactured along across-layer (AL) orientations, the impact of part orientation during turning is minimized and machined surface integrity is improved.

“…There are some sustainability models that involve product design elements as one of the improvement parameters for achieving more sustainable unit processes [54][55][56][57]. Most of the developed models have revolved around specific machining processes, such as turning, grinding, or milling [29,31,[58][59][60][61][62][63]. Lu et al [31] proposed a metrics-based approach to assess the sustainability performance of a drilling process according to sustainable manufacturing elements, as shown in Figure 3.…”

A General Framework for Sustainability Assessment of Sheet Metalworking Processes

et al. 2020

The sheet metalworking industries possess minimal knowledge in the area of sustainability despite having served as sub-contractors to various industrial sectors. This also highlights that suitable indicators for measuring the sustainability performance of sheet metalworking operations are poorly addressed. As sustainability assessment is regarded as a vital part of sustainable development, this paper has been aimed at establishing a general framework for sustainability assessment of sheet metalworking processes. The main attention was paid to two important processes—the cutting operations with a CNC turret punch press machine and sheet metal bending operations with CNC press brake machine. Stepwise guidelines to implement the proposed framework in sheet metalworking industries are consequently presented. Besides, this study contributes to developing an applicable sustainability indicator set for assessing such manufacturing processes. It makes a valuable contribution to advancing the narrow body of knowledge on the under-researched scope.

“…In contrast, the efforts done to assess the sustainability at the process level are relatively limited, and most of them concentrated mainly on specific machining processes such as turning, milling or grinding [23,25,29,31,[44][45][46]. Bhanot N. et al…”
