 STC A 

Industrial Product-Service Systems — IPS2
H. Meier (2), R. Roy (2), G. Seliger (1)  
STC A,  59/2/2010,  P.607
Keywords: Service, Lifecycle, Industrial Product-Service Systems
Abstract : In mechanical engineering and plant design, product-related services are usually considered as an add-on to the actual product. Industrial Product-Service Systems deal with dynamic interdependencies of products and services in production. Research areas cover new concepts and methods which enable the machine producers to design the potential services in an optimal way, already during the development of the machine. This paradigm shift from the separated consideration of products and services to a new product understanding consisting of integrated products and services creates innovation potential to increase the sustainable competitiveness of mechanical engineering and plant design. The latter allows business models which do not focus on the machine sales but on the use for the customer e.g. in form of continuously available machines. The business model determines the complexity of delivery processes. Characteristics of Industrial Product-Service Systems allow covering all market demands.

 STC C 

Advanced monitoring of machining operations
R. Teti (1), K. Jemielniak (1), G. O'Donnell, D. Dornfeld (1)  
STC C,  59/2/2010,  P.717
Keywords: Machining, Sensor monitoring, Advanced signal processing
Abstract : CIRP has had a long history of research and publication on the development and implementation of sensor monitoring of machining operations including tool condition monitoring, unmanned machining, process control and, more recently, advanced topics in machining monitoring, innovative signal processing, sensor fusion and related applications. This keynote follows a recent update of the literature on tool condition monitoring and documents the work of the cutting scientific technical committee in CIRP. The paper reviews the past contributions of CIRP in these areas and provides an up-to-date comprehensive survey of sensor technologies, signal processing, and decision making strategies for process monitoring. Application examples to industrial processes including reconfigurable sensor systems are reported. Future challenges and trends in sensor based machining operation monitoring are presented.

 STC Dn 

Design verification and validation in product lifecycle
P.G. Maropoulos (1), D. Ceglarek (1)  
STC Dn,  59/2/2010,  P.740
Keywords: Design, Validation, Verification, Lifecycle management
Abstract : The verification and validation of engineering designs are of primary importance as they directly influence production performance and ultimately define product functionality and customer perception. Research in aspects of verification and validation is widely spread ranging from tools employed during the digital design phase, to methods deployed for prototype verification and validation. This paper reviews the standard definitions of verification and validation in the context of engineering design and progresses to provide a coherent analysis and classification of these activities from preliminary design, to design in the digital domain and the physical verification and validation of products and processes. The scope of the paper includes aspects of system design and demonstrates how complex products are validated in the context of their lifecycle. Industrial requirements are highlighted and research trends and priorities identified.

 STC E 

Tip-based nanomanufacturing by electrical, chemical, mechanical and thermal processes
A.P. Malshe (2), K.P. Rajurkar (1), K.R. Virwani, C.R. Taylor, D.L. Bourell, G. Levy (1), M.M. Sundaram, J.A. McGeough (1), V. Kalyanasundaram, A.N. Samant  
STC E,  59/2/2010,  P.628
Keywords: Manufacturing, Nanomanufacturing, Tip-based nanomanufacturing
Abstract : Nanomanufactured products with higher complexities in function, materials, scales and their integration demand an increasing need for advanced manufacturing tools. It is driven by applications such as ultradense memory, individualized biomedicine and drug delivery, molecular reading and sorting, and nanoscale circuitry. The tip-based nanomanufacturing (TBN) platform represents a potent gamut of processes for such applications – performing various nanoscale manufacturing operations including machining, depositing, patterning, and assembling with in situmetrology and visualization. This keynote paper presents a comprehensive overview of TBN processes based upon ‘‘nanotool tips applying electrical, electrochemical, mechanical, electromagnetic and other forces to perform manufacturing operations.

 STC F 

Environmentally benign tribo-systems for metal forming
N. Bay (1), A. Azushima (1), P. Groche (2), I. Ishibashi, M. Merklein (2), M. Morishita, T. Nakamura, S. Schmid, M. Yoshida  
STC F,  59/2/2010,  P.760
Keywords: Metal forming tribology, Lubricants, Environmental impact, Tool materials, Tool coatings, Structured workpiece surfaces, Structured tool surfaces
Abstract : The growing awareness of environmental issues and the requirements to establish solutions diminishing the impact on working environment as well as external environment has initiated ever increasing efforts to develop new, environmentally benign tribological systems for metal forming. The present paper gives an overview of these efforts substituting environmentally hazardous lubricants in cold, warm and hot forging as well as sheet forming and punching/blanking by new, less harmful lubricants and furthermore describes other more generic measures directed towards the same goal such as development of antiseizure tool materials and coatings and application of structured workpiece and tool surfaces.

SPECIES — Co-evolution of products, processes and production systems
T. Tolio (1), D. Ceglarek (1), H.A. ElMaraghy (1), A. Fischer (1), S.J. Hu (1), L. Laperriere (2), S.T. Newman (2), J. Vancza (1)  
STC O,  59/2/2010,  P.672
Keywords: Product–process–system, Co-evolution, Factory of the future
Abstract : Manufacturing enterprises are changing the way they behave in the market to face the increasing complexity of the economic, socio-political and technological dynamics. Manufacturing products, processes and production systems result in being challenged by evolving external drivers, including the introduction of new regulations, new materials, technologies, services and communications, the pressure on costs and sustainability. The co-evolution paradigm synthesises the recent scientific and technical approaches proposed by academic and industrial communities dealing with methodologies and tools to support the coordinated evolution (co-evolution) of products, processes and production systems. This paper aims at reviewing and systemising the research carried out in the field of manufacturing coevolution with a particular focus on production systems. An introductory investigation of various industrial perspectives on the problemof co-evolution is presented, followed by the description of the coevolution model and the methodology adopted for framing the existing scientific contributions in the proposed model. Then, the core part of the work is presented, consisting in a systemised analysis of the current methodologies dealing with co-evolving product, process and system and a description of problems that remain unsolved, thus motivating future research strategies and roadmaps.
