The algorithm we propose calculates the environmental burden due to machine tool operations. The environmental burden analyzer we then developed determines the environmental impact of dry machining, minimum quantity lubricant (MQL) machining, and wet machining on the impact categories of global warming, acidification, eutrophication, photochemical oxidants, human toxicity, and ecotoxicity. We explain the features of impact categories as they relate to machining operations and discuss machining methods for lower the environmental burden of machine tool operations.
