“…Sarwar et al (2009) have chosen Specific Cutting Energy (SCE) as the pertinent parameter for measuring the efficiency of the metal cutting process. They stated that the variation of SCE as function of different workpiece materials can provide useful information that enables estimating machinability characteristics for selected workpieces.…”

“…As inferred in [19], the absolute cutting forces |F| according to the theoretical predictions are inversely proportionate to the cutting speed v c . Indeed, the mean absolute cutting force values estimated from the cutting force F(t) measurements at v c1 and v c3 were |F|=360 N and |F|=301 N, respectively.…”

“…Subtractive processes, such as machining, form an important substitute technology to metallic AM. They are the subject of a number of studies assessing the relationship between energy inputs and process parameters (Dietmair and Verl ; Kara and Li ; Rajemi et al ; Sarwar et al ). For the analysis of electrical energy requirements of various manufacturing processes, Gutowski and colleagues () propose a general framework using the concept of exergy.…”

Keywords:digital supply chain energy consumption industrial ecology manufacturing process rapid manufacturing rapid prototyping SummaryThe supply chains found in modern manufacturing are often complex and long. The resulting opacity poses a significant barrier to the measurement and minimization of energy consumption and therefore to the implementation of sustainable manufacturing. The current article investigates whether the adoption of additive manufacturing (AM) technology can be used to reach transparency in terms of energy and financial inputs to manufacturing operations.AM refers to the use of a group of electricity-driven technologies capable of combining materials to manufacture geometrically complex products in a single digitally controlled process step, entirely without molds, dies, or other tooling. The single-step nature affords full measurability with respect to process energy inputs and production costs. However, the parallel character of AM (allowing the contemporaneous production of multiple parts) poses previously unconsidered problems in the estimation of manufacturing resource consumption.This research discusses the implementation of a tool for the estimation of process energy flows and costs occurring in the AM technology variant direct metal laser sintering. It is demonstrated that accurate predictions can be made for the production of a basket of sample parts. Further, it is shown that, unlike conventional processes, the quantity and variety of parts demanded and the resulting ability to fully utilize the available machine capacity have an impact on process efficiency. It is also demonstrated that cost minimization in additive manufacturing may lead to the minimization of process energy consumption, thereby motivating sustainability improvements.
