“…For the metallic material, the SEC of subtractive manufacturing processes varies greatly with the different material. The milling and turning processes of AISI 4140 steel were estimated to be 1.45 × 10 4 J/cm 3 (milling) and 7.1~14.5 × 10 3 J/cm 3 (turning) [36,37] respectively, which only accounts for 0.75% to that of LENS process. Therefore, the traditional bulk forming process for polymer material and subtractive manufacturing process for metallic material are more energy efficient than the corresponding AM processes regarding the SEC when the material preparation process is out of consideration.…”

This paper explores the specific energy consumption (SEC) and environmental impacts for typical additive manufacturing processes. Also, the paper examines the possibility that ensure the product quality while reducing energy consumption with experimental analysis. The results show that (1) the SEC of additive manufacturing processes is related not only to material characteristics but also to the process input parameters; (2) it is possible to increase the energy efficiency without reducing product quality by adjusting the process rate or selecting different materials; and (3) the global warming potential (GWP) result of AM processes indicates that the GWP is brought about principally by the energy production process. The information provided by this project can also be of benefit to life cycle assessment and other environmental impact assessment related to AM processes.

“…The work recommended synchronization of spindle acceleration with a feed system to minimize energy consumption. Neugebauer et al 21 performed drilling and turning experiments to investigate energy efficiency in machine tools by focusing on tool selection and associated process parameters. The study revealed that tool selection and cutting parameters, specifically feed rate, play a key role toward energy efficiency of machine tools.…”

Drilling operations are one of the most commonly used operations in the automotive and aerospace sectors. The aim of this article is to compare peck drilling as an alternate approach to the conventional drilling and reaming operations; in terms of energy consumption and machined surface roughness to facilitate the selection of the optimum finishing processes with respect to machined surface quality and energy consumption. The experiments were performed under dry conditions on an Al-6061 using a high-speed steel reamer and drills of 12 mm diameter. The results revealed that peck drilling refined the surface finish of previously drilled steps in most of the cases. The outcome of the energy consumption analysis was used to evaluate the amount of CO 2 emissions. The study suggested that surface roughness refinement in peck drilling was better than conventional drilling but was not as efficient as the reaming process. Peck drilling generated surfaces with a roughness value between those of drilling and reaming operations. Less tool wear was observed under peck drilling process when compared with conventional drilling. The investigation also revealed that CO 2 emissions produced under peck drilling approach were slightly higher than for combined drilling and reaming approach.

“…Avram and Xirouchakis (2011) specifically concentrated on the variable mechanical energy requirements of the spindle and feed axes by taking into account the steady-state and transient regimes to estimate the use phase energy consumption of a machine tool system. Neugebauer et al (2011c) illustrated the importance of tool selection and the associated selection of process parameters to the subsequent energy efficiency of the drilling and turning operations. However, few efforts were received to combine energy efficient consideration during operation stage with the view of product life cycle, nor the changes that could realize the energy benefits.…”
