“…Several researchers, such as Jeswani [12], Wong et al [13], Kumar et al [14], and Han et al [15] used graphite powder for EDM of DTM materials and found it significantly useful. This process assisted us in selecting the graphite powder as abrasive in EDM of WC-Co. Table 1 [3,[17][18][19][20][21][22][23][24][25][26][27][28] describes the work done and gaps in literature with respect to EDM of WC. Jeswani [12] investigated EDM with distilled water and kerosene oil as dielectric fluid.…”

“…Many studies have reported on the production and related aspects of the EDM process, but only a few studies [22][23][24][25][26][27] that considered the environmental, safety, and health hazards of the EDM process were undertaken. Furthermore, studies presented in the literature focused on the effects of a single dielectric fluid, namely, kerosene oil; no study has investigated the effects of different dielectric fluids, especially water-based dielectric fluids for the EDM process.…”

Electrical discharge machining (EDM) is a well-known nontraditional manufacturing process to machine the difficult-to-machine (DTM) materials which have unique hardness properties. Researchers have successfully performed hybridization to improve this process by incorporating powders into the EDM process known as powder-mixed EDM process. This process drastically improves process efficiency by increasing material removal rate, micro-hardness, as well as reducing the tool wear rate and surface roughness. EDM also has some input parameters, including pulse-on time, dielectric levels and its type, current setting, flushing pressure, and so on, which have a significant effect on EDM performance. However, despite their positive influence, investigating the effects of these parameters on environmental conditions is necessary. Most studies demonstrate the use of kerosene oil as dielectric fluid. Nevertheless, in this work, the authors highlight the findings with respect to three different dielectric fluids, including kerosene oil, EDM oil, and distilled water using one-variable-at-a-time approach for machining as well as environmental aspects. The hazard and operability analysis is employed to identify the inherent safety factors associated with powder-mixed EDM of WC-Co.

“…Conclusions In addition, the accruing availability of data for a range of similar machines (same process, different suppliers and machine capacities) will allow the establishment of parametric emission and resource use estimation models for a more streamlined LCA of products including reliable manufacturing process data. Both approaches have already provided useful results in some initial case studies (Kellens et al 2009;Duflou et al (Int J Sustain Manufacturing 2:80-98, 2010); Santos et al (J Clean Prod 19:356-364, 2011); UPLCI 2011; Kellens et al 2011a) and the use will be illustrated by two case studies in Part 2 of this paper (Kellens et al 2011b).…”

Purpose This report proposes a life-cycle analysis (LCA)-oriented methodology for systematic inventory analysis of the use phase of manufacturing unit processes providing unit process datasets to be used in life-cycle inventory (LCI) databases and libraries. The methodology has been developed in the framework of the CO 2 PE! collaborative research programme (CO2PE! 2011a) and comprises two approaches with different levels of detail, respectively referred to as the screening approach and the in-depth approach. Methods The screening approach relies on representative, publicly available data and engineering calculations for energy use, material loss, and identification of variables for improvement, while the in-depth approach is subdivided into four modules, including a time study, a power consumption study, a consumables study and an emissions study, in which all relevant process in-and outputs are measured and analysed in detail. The screening approach provides the first insight in the unit process and results in a set of approximate LCI data, which also serve to guide the more detailed and complete in-depth approach leading to more accurate LCI data as well as the identification of potential for energy and resource efficiency improvements of the manufacturing unit process. To ensure optimal Responsible editor: Martin Baitz Preamble. The CO 2 PE! UPLCI-Initiative aims to document and improve the environmental impact created during the use phase of a wide range of discrete part manufacturing processes. This article is the first of two and describes the developed methodology comprising two approaches with different levels of detail. The second paper provides for both approaches a case study of the Life Cycle Inventory step.Electronic supplementary material The online version of this article (

“…1 Process from an energy point of view [3] conventional processes, such as forming [7][8][9] or materialremoving processes [9][10][11][12][13][14], have recently collected some interest. There are fewer studies on nonconventional processes, namely EDM [15,16] or laser machining [9,17,18]. There is also research done on real-time energy consumption measurement [19,20], which is necessary for the implementation of energy-efficient production strategies.…”

Energy efficiency has become a very significant factor, requiring its inclusion in the manufacturing decision-making attributes. This paper proposes a generalized approach to manufacturing energy efficiency. The basic element of the approach is the division of energy efficiency definition and study into four manufacturing levels, namely process, machine, production line, and factory. Process-level definitions are provided for the majority of manufacturing processes. A machine-level study indicates and solves difficulties, generated by the workpiece geometry, and points out the interaction with the process level through factors, such as the process time. Moreover, machine tool peripherals are responsible for a significant portion of the consumed energy, and classification based on the dependence of their consumption on process variables is required. Studies made on the production line and factory levels show that energy efficiency, at these levels, is heavily dependent on production planning and scheduling and can be improved through the appropriate utilization of machines, with the inclusion of shutdown and eco-modes. Finally, a case study is presented, showing that many of the difficulties towards the optimization of energy efficiency can be dealt with successfully, using the proposed generalized approach.
