Recent Advances in Modelling of Metal Machining Processes
P.J. Arrazola (2) , T. Özel, (2) , D. Umbrello (2), M. Davies (1) , I.S. Jawahir (1)  
STC C,  62/2/2013,  P.695
Keywords: Modelling, Machining, Chip formation
Abstract : During the last few decades, there has been significant progress in developing industry-driven predictive models for machining operations. This paper presents the state-of-the-art in predictive performance models for machining, and identifies the strengths and weaknesses of current models. This includes a critical assessment of the relevant modelling techniques and their applicability and/or limitations for the prediction of the complex machining operations performed in industry. This paper includes contributions from academia and industry, and is expected to serve as a comprehensive report of recent progress, as well as a roadmap for future directions. Process models often target the prediction of fundamental variables such as stresses, strains, strain-rates, temperatures etc. However, to be useful to industry, these variables must be correlated to performance measures: product quality (accuracy, dimensional tolerances, finish, etc.), surface and subsurface integrity, tool-wear, chip-form/breakability, burr formation, machine stability, etc. The adoption of machining models by industry critically depends on the capability of a model to make this link and predict machining performance. Therefore, this paper would identify and discuss several key research topics closely associated with predictive model development for machining operations, primarily targeting industry applications.

 STC Dn 

Open Architecture Products
Y. Koren (1), J. Hu (1), P. Gu (1), M. Shpitalni (1)  
STC Dn,  62/2/2013,  P.719
Keywords: Open-Architecture, Assembly, Design
Abstract : This paper defines Open-Architecture Products (OAPs), a new class of products comprising a fixed platform and modules that can be added and swapped. Customers can adapt OAPs to their needs by integrating modules into the platform. Manufacturers will produce these platforms, while new small companies and customers will develop the modules, thus increasing employment and causing the economy to flourish. At the same time OAPs will provide consumers with the product they desire. Challenges include developing new OAP design software for non-professional designers and new assembly systems to facilitate economical assembly of a large number of product variants.

 STC E 

Modeling of ECM and EDM Processes
S. Hinduja (1), M. Kunieda (1)  
STC E,  62/2/2013,  P.775
Keywords: ECM, EDM, Modelling
Abstract : The modelling of ECM and EDM processes requires not one but several models to simulate the different phenomena that occur during machining. This paper reviews the models that have been developed to simulate each of these phenomena, e.g. potential models to calculate the current density distribution in ECM, thermal models for the plasma arc in EDM, moving boundary models to simulate the anodic dissolution in ECM and probabilistic models to determine the discharge location in EDM. In addition to discussing the relative merits of the techniques deployed in these models, the paper describes some salient applications and concludes with desirable future enhancements to these models.

STC F,  62/2/2013,  P.673
Keywords: Joining, Plastic deformation, Forming
Abstract : As the scale and complexity of products such as aircraft and cars increase, demand for new functional processes to join mechanical parts grows. The use of plastic deformation for joining parts potentially offers improved accuracy, reliability and environmental safety as well as creating opportunities to design new products through joining dissimilar materials. This paper aims to provide an overview of the state of the art in such joining processes, including cold welding, friction stir welding, self-pierce riveting, mechanical clinching and joining by forming. The paper includes description of the mechanism of joint formation, and analysis of joint performance and applicability.

The approach to sustainability includes environmental, social, and economic sustainability in accordance with the definition proposed in the Brundtland Report of the United Nations [156]. The main focus is on environmental and social sustainability. Economic sustainability will be considered as manufacturing productivity.

Machine tools for large parts
L. Uriarte (3), M. Zatarain (1), D. Axinte (1), J. Yague-Fabra (2), S. Ilhenfeldt (3), J. Eguia, A. Olarra  
STC M,  62/2/2013,  P.731
Keywords: Machine tool, Calibration, Portable machine
Abstract : This paper reviews the design, engineering principles and applications of machine tools specially developed for large parts. Large workshop machines are commonly used for manufacturing, where the impact of the general engineering principles differs substantially from those applied to conventional size machines. Portable machines are used during assembly and operation due to mobility, agility and energy constraints. Such large dimensions produce an amplification factor of any error source, so verification and calibration of such large or portable machines becomes even more critical than in conventional machines. The paper also includes future trends and unsolved challenges.

STC S,  62/2/2013,  P.607
Keywords: Surface, Nano manufacturing, Bio-inspired
Abstract : Over millions of years, biological subjects have been in continuous combat with extreme environmental conditions. The fittest have survived through continuous evolution. In particular, biological surfaces, which are the active interfaces between subjects and the environment, have evolved to a higher state of intelligent functionality. These surfaces became more efficient by using combinations of available materials, along with unique physical and chemical strategies. Noteworthy physical strategies include features such as texturing and structure, and chemical strategies such as sensing and actuation. These strategies collectively enable functional surfaces to deliver extraordinary adhesion, hydrophobicity, multispectral response, energy scavenging, thermal regulation, antibiofouling, and other advanced functions. Production industries have been intrigued with such biological surface strategies in order to learn clever surface architectures and implement those architectures to impart advanced functionalities into manufactured consumer products. This keynote paper delivers a critical review of such inspiring biological surfaces and their nonbiological product analogues, where manufacturing science and engineering have adopted such advanced functional surface architectures.
