Keywords: Assembly, CAD model, Simulation |
Abstract : This paper reviews the state-of-the-art methodologies for developing computer-aided design (CAD) model based systems for assembly
simulation, planning and training. Methods for CAD model generation from digital data acquisition, motion capture, assembly modeling, humancomputer
interface, and data exchange between a CAD system and a VR/AR system are described. Also presented is an integrated methodology
for designing, planning, evaluating and testing assembly systems. The paper further describes the implementation of these methods and
provides application examples of CAD model based simulation for virtual assembly prototyping, planning and training. Finally, the technology

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.

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, 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.

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.

Abstract : This paper presents an overview of research on sustainability of abrasive processes. It incorporates results from a round robin study on “energyefficiency
of abrasive processes†which has been carried out within the scientific technical committee “abrasive processes†(STC G) of CIRP, the content of
technical presentations in STC G, and the results of a comprehensive literature study. 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.

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.

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.
