Sustainability is an important issue in manufacturing technologies in these days. However, for manufacturing engineers, quality has been the most important goal for long. Thus, in evaluating sustainability of manufacturing technologies, not only environmental aspects, but also quality of manufacturing should be taken into account. The existing work has proposed an evaluation method for manufacturing technologies which was named "Total Performance Analysis (TPA)." It can quantify the balance of the value created by the manufacturing process versus the cost and environmental impact. TPA can point out segment manufacturing processes which should be improved most. Through a simple case study, the paper concludes that the proposed method is helpful to evaluate real sustainability of manufacturing processes. In addition, by combining with manufacturing technologies database, not only pointing out the manufacturing processes to be improved, but also suggesting alternative processes will be possible.
