The Autonomic Object (AO) based on autonomic computing is embedded in the nodes of flexible workflow to ensure the intelligence of the framework. An innovative flexible workflow modelling method based on dynamic instance creation is proposed as part of the EnDesProM. Both the formalised definition and graphical expression of the EDP models are introduced to ensure the rigor of the approach. The architecture of the intelligent workflow is designed and the application of the weighted Certainty Factor (CF) model in the knowledge expression is investigated to deal with the incomplete information in EDP. The EnDesProM has been evaluated through an EDP in a Make-to-Order (MTO) company and the results show that EnDesProM can support the creative and dynamic EDP satisfactorily, though further improvements are required.

Positioning the NMIS and MSA development as an advanced digital and cyberphysical asset, which can be leveraged by established educational institutes, is a fundamental aspect of this proposition. Having a robust evidence base to inform how it can best achieve its objectives is an important element of the NMIS strategic vision and planned operational delivery. This research report adds to this evidence base, and proposes a new pedagogical model for delivering advanced manufacturing skills in Scotland, and specifically an MSA delivery model.

Central to successful ISD is the coordination and incorporation of contributions from many professions and technologies. This presents challenges for organisations in the composition and supporting of integrated systems. One challenge is that many engineering graduates enter industry with little or no explicit knowledge of ISD and systems thinking. This in turn results in reduced organisational efficiency and increased post employment training. The hypothesis is simple; provide engineering students with ISD principles and you will provide organisations with graduates who can contribute to industry quicker. The Royal Academy of Engineering appointed a Visiting Professor at the University of Strathclyde, with the overall aim to produce a pilot scheme integrating systems design education into engineering programmes. This paper charts the key project findings, beginning with a review of ISD practice within industry and academia. From this review, an analysis matrix was developed and piloted allowing Universities to analyse the extent ISD is being taught and identify gaps in knowledge.

Failures by fracture due to high deformation can be unexpected and sometimes catastrophic, causing tool damage. If process failures can be identified in real time, an automatic cutout could prevent costly tool damage. Sound and vibration monitoring is well established and commercially viable in the machining sector to detect current and incipient process failures, but not for FF. A broad-frequency microphone was used to record the sound signature of the manufacturing cycle for a series of FF parts. Parts were flow formed using single and multiple passes, and flaws were introduced into some of the parts to simulate the presence of spontaneously initiated cracks. The results show that this methodology is capable of identifying both introduced defects and spontaneous failures during flow forming. Further investigation is needed to categorise and identify different modes of failure and identify further potential applications in rotary forming.

Cold roll forming is an incremental sheet metal forming process used to supply products to numero... more Cold roll forming is an incremental sheet metal forming process used to supply products to numerous industries such as automotive, architecture and construction, etc. In recent years there has been an increase in the demand by customers for high value products, through the forming of high strength materials, or complex profiles. Such demands increase the challenges faced by the tooling designer to bring a successful product through from design to manufacture, on time and within specification. Finite element (FE) simulations are increasingly applied in industry due to the desired advantage of reducing design iterations by allowing the designer to investigate the effects of parameter changes, without the risk of expensive tooling costs. Some successful validation of the numerical modelling of the cold roll forming process can be found in literature, in particular when analysing the strain distribution across the material or comparing the final rolled profile geometry. However, cold roll forming is a continuous process and no one has published work on the measurement of the profile on a pass to pass basis, in particular, the three dimensional geometry of the profile. Experimental trials were carried out to obtain a 3D point cloud model of the top surface of a roll formed section. This investigation aimed to quantify how accurate FE simulation may be in relation to physical data.

Refractory ceramics are a low cost option to substitute the high temperature resistant steels and other alloys conventionally used in SPF dies, but their brittle nature is a limiting factor for most SPF applications. Suitable surface coatings have shown a significant effect on wear resistance and can be employed to improve the ceramic performance in terms of tool life. This paper is focused on an initial study on protective coatings for SPF ceramic dies to evaluate their effectiveness for SPF forming. The tests were conducted using a dedicated test rig built at the Advanced Forming Research Centre (AFRC) at the University of Strathclyde, and where the die-blank interaction under SPF conditions was replicated at laboratory scale.

Ceramic dies are an emerging technology in the SPF domain, as they have a lower production cost than conventional metal tools, and have short lead-times, but their brittle nature is a limiting factor for SPF applications. Suitable surface treatments have a remarkable effect on wear resistance; hence, the scope of the research is to investigate a suitable coating solution to improve the working surface wear resistance, increasing the lifetime of the SPF ceramic dies.

It is generally used for aerospace applications, and due to its remarkable abilities, it is crucial to improve the tool manufacturing lead-time and lifetime to make the SPF applicable for further industrial applications. Recently, high temperature resistant steel dies are being replaced with emerging materials such as refractory ceramics. Ceramic dies have a lower production cost and have short lead-times, but their brittle nature is a limiting factor for SPF applications. Surface treatments can have a catalytic effect on the mechanical properties of the working surface of the die. Different materials can be used as coatings to further reduce die wear, so coatings need to be tailored to the final application. This study will be performed at the Advanced Forming Research Centre and it will consist on the development of a surface wearing monitor method for ceramic dies and, at a later stage, to develop and implement a cost-effective coating for the lifetime improvement of ceramic dies.

Suitable surface treatments have a remarkable effect on wear resistance; hence, the scope of the research is to investigate a suitable coating solution to improve the working surface wear resistance, increasing the lifetime of the SPF ceramic dies. The research is currently focused on the evaluation of a range of coatings for ceramic dies under SPF conditions. The initial trials are in curse using a previously developed test protocol on laboratory scale dies (Staiano et al., 2014). Depending on the resulting coating protection properties, the research project will move into trials under production conditions in a 200tonn SPF press, or in the optimisation of the coating deposition procedure. The aim of the research is to improve ceramic die lifetime, enabling their employability in hot forming processes.

This paper presents the current data concerning Laser Metal Deposition deployment conditions and their relationship to material microstructure evolution and mechanical properties. The study highlights the need for experiments involving scan path geometry and topology and details the experiments currently in preparation.

From social justice in the workplace to philanthropic activities, these growing demands can become a burden for some organisations, as new regulations are constantly being introduced to satisfy our global needs. This pressure is greater for SMEs as they have considerably fewer resources in terms of time, funds and knowledge to adapt to these changes. This situation is aggravated by the fact that a majority of SMEs are unaware of their societal and environmental impacts, thus making them more susceptible to fail to meet the demands of a highly competitive and regulated market. Institutions of Higher Education are aware of the above and have tried to introduce education in the area of Corporate Social Responsibility (CSR) in the curricula of engineering students. However, the introduction of this material has not produced the desired effect. Therefore, it is the purpose of this research project to; increase awareness of sustainable CSR practices in SMEs by illustrating that these practices can lead to profit rather than costs, and to highlight the need to integrate CSR as a fundamental area of study in the education of engineering students. The results will be used to develop a model aimed at facilitating the implementation of CSR practices in SMEs. Additionally, teaching material will be produced with the hope that this information will be included in the curriculum of engineering students in the near future.

Many large companies such as Land-Rover, General Motors and Xerox have fully documented design processes and are quick to highlight their benefits. Yet, there are many more medium and small companies still performing design in a rather ad hoc manner-why should this be? While there are some cases of companies who "do not have time" for such modern ideas, there are many more who appreciate the benefits but either do not know how to get started, are confused by the array of choices, or have tried to implement a new process and failed. Like total quality management, implementing a new design process requires more than just a change in practices; it calls for a change in attitudes and often organizational changes as well.
