Multi-Objective Tooling Optimization for Sustainable Manufacturing

Process planning is an activity for designers to evaluate manufacturability and manufacturing cost in the early design stage of mechanical parts production where important parameters that affect the machining process should be analyzed in detail. This paper deals with the systematic determination of the detailed methods involved in the manufacturing of parts from raw materials to a finished product using fuzzy optimization to minimize its impact on the environment. The focus of this study is to develop a fuzzy optimization model for environmental supportive process planning while minimizing the factors such as machining cost, machining time and environmental impact for turning operation. A multi-objective non-linear programming model is also developed and its results are compared with the fuzzy model.
