“…On the highly aggregated enterprise level, Yeo and Neo (1998) integrated a hazard scoring model into the selection of a welding process. This was extended to the broader scope of thin aluminum sheet joining by Chien et al (2012), who evaluated technologies with respect to costs, greenhouse gas emissions and performance standards. However, these works focus on decision support oriented systems and hence do not evaluate the processes in-depth.…”

“…Global challenges require the implementation of energy efficient manufacturing methods and economical concepts to preserve natural resources. Therefore industrial applications increasingly consider methods such as additive manufacturing or lightweight design, which are promising technological approaches to meet prospective economical and ecological aspects [1,2]. However, the usage of lightweight design also requires the development of appropriate joining technologies such as FSW.…”

Friction stir welding (FSW) has developed into a reliable and increasing used industrial joining technology. Various tool configurations can be used for FSW, each of which has advantages and challenges. State-of-the-art FSW employs various tool configurations, including the conventional, the stationary shoulder, and the dual-rotational configuration which is characterized by separate control of shoulder and probe. In this study, an innovative method to combine various tool configurations was developed by a novel FSW spindle stack construction. With an additional servomotor, existing FSW systems can be extended by separate control of shoulder and probe so that varying rotational speeds and rotational directions can be set. This allows enhanced possibilities (a) to adjust frictional heat generation and (b) to apply several tool configurations. The main advantages of this enhanced type of FSW are demonstrated in three ways: increased weld penetration depth, reduction of undesirable machine vibrations, and the combination of varying tool configurations such as stationary shoulder and conventional FSW. The investigations were carried out with 2-mm EN AA 5754 H22 sheets and performed on a robotized FSW setup.

“…In the mechanical product design Deng et al considered the integration of environmental (LCA) and economic benefit (LCC) as objective of the multi-disciplinary optimization [24] [25]. Finally, Chien et al conducted a multi-objective analysis on joining technologies based on two parameters: LCA and LCC [26].…”

Nowadays, the worldwide economic downturn lead the manufacturer and their suppliers to cut costs and enhance the performances. In addition, environmental protection is becoming more and more important and green manufacturing got an expected practice. Based on those recognitions, in the early stage of product design environmental impacts must be weighted, balanced and optimized against other concerns, such as Life Cycle Costs (LCC), availability, time to market, etc. These multiples and often conflicting objectives pose a challenging and complex optimization problem. Thus, the focus is moved from the single methodology towards the integration and optimization of all of them together. With this aim a new term, Product Life Cycle Optimization (PLCO), has been coined in order to identify those kind of problem. The aim of the paper is to propose a PLCO multi-objective model that optimizes simultaneously, along the product life cycle, costs, environmental impacts and performance values. The model is developed with two open-source Java based frameworks
