Evaluating Process Design through Quality Function Deployment for Environment

Quality Function Deployment for Environment (QFDE) is an effective eco-design tool to transform the voices of customer and environment into the engineering metrics for evaluating product design. From the viewpoint of green manufacturing, machining process design is focused on by many manufacturers and it is necessary to evaluate its environmental impact. The QFDE method is developed to evaluate machining process design with the new house of quality. According to the evaluation, design engineers can identify which part characteristics and their machining processes should be focused on and then know how to improve the product design. A case of an engine is studied to illustrate the proposed method.
