“…In the manufacturing industry, AHP has been used for various types of decision analysis, such as LCA-based decision making for the foundry industry (Saha and Wang 1996), in evaluating and prioritizing machine fluids based on savings in resources and reduction of waste (Yeo and New 1999), and the integrated AHP and LCA approach in a multiple criteria decision problem to evaluate economic, functional, and environ-mental costs and benefits of alternative materials in the packaging industry (Deshmukh and Wang 1996). Madu and colleagues (2002) adopted an integrated approach using AHP and quality function deployment to match product design requirements and customer requirements in the environmentally conscious design of recycled paper products.…”

Summary This article addresses the need for a structured and compre‐hensive methodology for assessing the environmental perfor‐mance of manufacturing processes. The analytic hierarchy pro‐cess (AHP) is used as the basic framework for analyzing environmental impacts and improvement options following a streamlined life‐cycle assessment (LCA) approach that is fo‐cused on the manufacturing operation. The multicriteria de‐cision analysis approach of the AHP is consistent with the LCA concept because the environmental factors can be hierarchi‐cally structured into impacts and improvement options. Its po‐tential as a valuation tool for impact and improvement assess‐ment addresses both qualitative and quantitative issues in environmental decision making. Through application to a pulp and paper manufacturing case study, the viability of the AHP for evaluating environmen‐tal impacts and prioritizing process improvement options rela‐tive to these impacts is demonstrated. AHP was used to pro‐vide a quantitative tool for the design of a set of weighting factors for impact and improvement analyses.

“…Several researchers used these techniques in environmental impact assessment and green manufacturing (Kuo, Chang, & Huang, 2006;Tesfamariam & Sadiq, 2006). Yeo and New (1999) used a prioritization matrix for dielectric selection in a die sinking EDM process. However, no reported literature on the optimization of process parameters for green EDM is available.…”

“…In EDM, the dielectric medium takes the main role in affecting the surface quality, material removal rate, and electrode wear during machining. The function of the dielectric fluid is a flushing medium, accelerating the energy density of the plasma channel, an insulator and cooling the electrodes [15,16]. In addition, dielectric fluid is an influential factor in the cost, productivity, and quality of the machined parts.…”

Water-in-sunflower seed oil emulsion as a dielectric fluid for micro electrical discharge machining (µEDM)

Dielectric fluid is an important component in machining using Electrical Discharge Machining (EDM). Conventional dielectric fluids have disadvantages such as emit carbon dioxide and carbon mono oxide gases to the environment. Vegetable-based dielectrics are biodegradable, environment-friendly, and emit less harmful gases. This study focuses on water-in-sunflower seed oil as a replacement for conventional dielectric fluid. The quality of the performance is evaluated through selected machining responses such as material removal rate (MRR), tool wear ratio (TWR), circularity, taper conicity, and overcut of the hole. The experimental design of the project is designed based on the Taguchi L 9 orthogonal array which results in 9 sets of experiments with different combinations of electrode diameter, dielectric fluids, feed rate, and capacitance. Water-in-sunflower seed oil provides the highest MRR. Besides that, it also performs well in the overcut which shows a steady spark throughout the whole fabrication.
