“…The results showed that the cryogenic cooling approach reduced production cost by 34% and 39% as compared to the dry and MQL approaches, respectively. Priarone et al [6] employed a bottom-up approach (BUA) to develop cost models for the dry and wet turning of Ti-6Al-4V alloys. Optimal cutting parameters were found for the minimum specific cost, production time, CO 2 emission, and energy consumption.…”

The quest for advanced cooling/lubrication approaches for energy-efficient, eco-benign, and cost-effective sustainable machining processes is garnering attention in academia and industry. Electrical and embodied energy consumption plays an important role in reducing CO2 emissions. In the present study, new empirical models are proposed to assess sustainable indicators. The embodied energy, environmental burden, and cost of coolant/lubricant have been added in the proposed models. Initially, optimal levels of minimum quantity lubrication (MQL) oil flow rate, liquid LN2 flow rate, air pressure, and nanoparticle concentration were found. Based on optimal technological parameters, experiments were performed under the same cutting conditions (machining parameters) for MQL and cryogenic LN2-assisted external turning of Ti6-Al-4V titanium alloy. The electric power and energy consumption, production time/cost, and CO2 emissions were assessed for a unit cutting-tool life. Later, specific responses were measured and compared between both cooling and lubrication approaches. Results showed that hybrid Al-GnP nanofluid consumed 80.6% less specific cumulative energy and emitted 88.7% less total CO2 emissions. However, cryogenic LN2 extended tool life by nearly 70% and incurred 4.12% less specific costs with 11.1% better surface quality. In summary, after Energy–Economy–Ecology–Engineering technology (4E)-based analysis, cryogenic LN2 is sustainable economically but not environmentally and there is a need to improve the sustainable production of LN2 at an industrial scale to achieve environmental sustainability. The present study provides useful information to establish clean machining processes.

“…13). The higher cutting speed can massively reduce the tool lifespan when turning difficult-to-cut materials (Priarone et al, 2018). In addition, when the cutting tool life decreases, the tool change times ( ) increases and more electrical energy is consumed due to increased tool change time (Li et al, 2016).…”

“…Alvarez et al (Álvarez et al, 2017) reviewed over 300 publications in the area of sustainable manufacturing engineering with the focus being on machining and they summarized published works in order to propose a unified framework, including the existing parameters and new ones, aimed at achieving integral sustainability in machining. Priarone et al (Priarone et al, 2018) described an approach to integrate the environmental and economic assessment of the machining process. Their work and assessment is based on considering one source (energy) and one type of environmental impact (CO2 emissions), suggesting that the range of process parameters that allow for maximum efficiency is influenced by material machinability.…”

Sustainability assessment of a manufacturing process is not an easy task and requires knowledge from inside of the process physics or chemistry as well as the overall process performance considering the effectiveness of the process and specific applications. Sustainability assessment is with increasing demand among the manufacturing companies. At present sustainability is considered only among the traditional manufacturing techniques and nontraditional processes do not receive enough attention in spite of the increasing demand for their use. Additionally micro and nano non-traditional manufacturing processes are nearly not considered in the studies for sustainability; and micro electrochemical machining (µECM) was not an exemption either. µECM is one of the promising non-conventional machining processes but its expensive structure, complex nature of the electrochemical reaction and process dependency on operator experiences has kept it back at research level. Securing a place for a new manufacturing process has to be done by proving its sustainability in comparison to the other existing processes.In this work, the aim is to establish a framework for assessment of the µECM sustainability based on five dimensions of the sustainability in order to justify its use and the initial investment cost. Indicators and measures for the effectiveness of the process are suggested as well as machining performance parameters are discussed . Routes for optimizing machining parameters is also explored. Finally the full picture sustainability assessment is generated.
