Abstract

Sustainable manufacturing aims to use fewer resources
and energy, and to produce less environmentally harmful waste and less
pollutants. Productive, scientific and research institutions have sought to
innovate and develop new production methods that contribute to improved
performance, profitability, quality improvement and adherence to sustainable
manufacturing requirements. Electric discharge machining (EDM) is used to
machine different types of materials especially hard material with high
precision. During EDM wastes and toxic emissions are released to cause negative
impact on the environment and operators health. The concentration these
undesirable products are affected by several factors, the most important of
which is the type of the dielectric or dry EDM or near-dry EDM. In this paper,
authors have reviewed studies which most of them focus on two sustainable
manufacturing indicators, machining performance and environmental impact of
using hydrocarbon based dielectric fluid and compared to bio-dielectric, water,
dry, and near-dry. It is concluded from these studies that there are
alternatives to EDM, and these alternatives give good machining results and
have less impact on the environment. To reduce the risk of the process requires
safety measures and some equipment and further researches in sustainable
manufacturing using EDM.
