The current work outlines an approach to close the loop between process planning and machine tool dynamic modeling by addressing the problem of energy efficiency across the process design and realization chains, from the process settings and pallet configuration to the machine tool design and usage phases. The proposed closed loop approach consists of an off-line and on-line component enabling ...

The success of a FE model for metal cutting process is strongly dependent on the accurate characterization of the workpiece material, under similar conditions as those found in metal cutting. In this paper, dynamic shear tests using a Gleeble machine have been performed on 4 mm thickness disks of AZ31B-O magnesium alloy, using a special designed tool. In order to include the effects of the cryo...

In current business environment many OEM companies are employing mass customization strategy, which has implication on the entire operations of an enterprise and especially influences the character of assembly processes. Increased product differentiation in context of customized production causes significant changes in complexity of assembly systems. Our focus in this paper is the development o...

Trauma is a major cause of systemic inflammatory response syndrome and multiple organ dysfunction syndrome. Macrophages (Mφ) direct trauma-induced inflammation, and Mφ death critically influences the progression of the inflammatory response. In the current study, we explored an important role of trauma in inducing mitochondrial DNA (mtDNA) damage in Mφ and the subsequent regulation of Mφ death....

The Assembly Line Balancing Problem (ALBP) is to determine the optimal allocation of assembly operations to a set of workstations, with respect to precedence constraints. This paper proposes a multi-objective optimization to solve the ALBP using a Genetic Algorithm (GA) approach. The aim is to minimize, besides the number of workstations, two aspects, very important from an economic point of vi...

Manufacturers expanding their business globally need to understand and analyze long-term trends of technology innovation relevant to their products as well as future socio-economic development of the target markets. Qualitative scenario modeling methods can evaluate opportunities and risks of their products in a specific market. To obtain quantitative evaluation results, however, just qualitati...

First step for the implementation of MC is to determine the desired level of product variety offered to customers (or customization degree). The right decision on the position of Customer Order Decoupling Point (CODP) is critical to determine the level of customization. . In this model, we develop two objective bases on company's profit and customer values perceived and analyze impacts single-C...

Pressure of emergent countries, policy makers and industrial companies’ interests are pushing European companies towards a high consideration of whole product life cycle. Designers and systems engineers are the main actors involved, due to their high influence on product life cycle costs and environmental impacts since early design phase. The aim of the paper is to propose an integrated, struct...

Todays efforts to optimize industrial production processes exceedingly focus on tools’ life cycle costs. Toolmaker and its customer are the two entities influencing tools’ life cycle costs. Due to lack of information exchange neither life cycle assessment nor cost efficient life cycles can be realized. An effective lever for penetrating information exchange and therefore gaining cost efficiency...
