It is widely recognized that industrial production inevitably results in an environmental impact. Energy consumption during production is responsible for a part of this impact, but is often not provided in cradle-to-gate life cycles. Transparent description of the transformation of materials, parts, and chemicals into products is described herein as a means to improve the environmental profile of products and manufacturing machine. This paper focuses on manufacturing energy and chemicals/materials required at the machine level and provides a methodology to quantify the energy consumed and mass loss for simple products in a manufacturing setting. That energy data are then used to validate the new approach proposed by (Overcash et.al, 2009a, and 2009b) for drilling unit processes. The approach uses manufacturing unit processes as the basis for evaluating environmental impacts at the manufacturing phase of a product’s life cycle. Examining manufacturing processes at the machine level creates an important improvement in transparency which aids review and improvement analyses.

Auch kleinere Unternehmen mit komplexen Herstellungsprozessen müssen heute in der Kleinserie die Effizienz und Geschwindigkeit in der Produktion erhöhen. Zentraler Bestandteil ist dabei eine schlanke Fertigungssteuerung in einem ganzheitlichen Produktionssystem. Der Fachbeitrag zeigt, wie auch bei hoher Komplexität wesentliche Ansätze der „Lean Production“ genutzt werden, um die Produktion von Ingenieurkeramiken durch die intelligente Vernetzung bereichsspezifischer Methoden zu optimieren.   Today, even small companies with complex manufacturing processes in low-volume production have to improve efficiency and speed in manufacturing. A core aspect is lean manufacturing control within an overall production system. This article shows how the main approaches of Lean Production can be applied even to a highly complex environment. The intelligent integration of specific methods for each control unit helps to enhance the production of ceramics.

New Framework

Currently, the adoption of a specific approach to business activities that highlights the strategic importance of corporate social responsibility hereafter CSR is the most important element influencing the existence and continuity of an organization. Thus, there is not a surprise that universities shall identify, in terms of own activities, the possibility to lead their orientation beyond teaching-learning process, towards the operations and institutional activities. At the same time, recent decades have experienced the failure of CSR as a way of doing business, govern or provide solutions and evaluate ethical issues and, thus, of the need to apply and implement a new approach - CSR 2.0. The transition from the current CSR, or 1.0, to CSR 2.0 requires the adoption of five new principles—creativity, scalability, responsiveness, glocality, and circularity—and embedding them within organizations management and culture. The paper will unfold towards two steps: the first, dedicated to the correlation between education (Blessinger's models and frameworks elements) with business (based on higher education business models), and the second, represented by integrating the new built model with the concepts and principles of CSR 2.0 developed by Visser. The new framework can be used to manage the context and processes of a socially responsible university as part of a world influenced by CSR 2.0 principles.

Teaching Learning

Cognitive approaches to teaching generate learning through the interaction between the subject and object of study. One of the strategies to create this interaction is related to the application of virtual and augmented reality in the teaching-learning processes. Through a systematic literature review, this work aims to describe the approaches used to measure the impacts on student learning who used virtual reality (VR) and augmented reality (AR) in the teaching-learning processes of engineering courses, the impacts on learning, and student satisfaction. The surveys showed that 70% of research analyzed, students who used virtual reality or augmented reality learned more, and 90% of the research described that students who used virtual or augmented reality were more satisfied with the new approach than the traditional teaching approach. The conclusion is that there are positive impacts, in the vast majority of cases, on learning and the satisfaction of students who use virtual or augmented reality in the teaching-learning processes applied in engineering courses.

Manufacturing Yield

Abstract Yielded cost is defined as cost divided by yield and can be used as a metric for representing an effective cost per good (non-defective) assembly for a manufacturing process. Although yielded cost is not a new concept, it has no consistent definition in engineering literature, and several different formulations and interpretations exist in the context of manufacturing and assembly. In manufacturing, yield is the probability that an assembly is non-defective. To find the effective cost per good assembly that is invested in the manufacturing or assembly process, cost is accumulated and divided by yield. This paper reviews and correlates existing yielded cost formulations and presents a new method that enables consistent measurement of sequential process flows. This new method views the yielded cost associated with an individual process step (step yielded cost) as the change in the process’s yielded cost when the step is removed from the process. This approach is preferred because it incorporates upstream and downstream information and because it provides a specific process step’s effective cost per good assembly that is independent of step order between steps that scrap defective product (i.e., test steps). Conventional wisdom dictates that the best way to improve a process is to increase the yield of the lowest yield step. The new approach developed in this paper produces an auxiliary cost that can be used to determine the best method of improving processes that, for complex processes, does not always correspond to improving the lowest yield step. Simple and complex assembly process examples are presented to demonstrate the interpretation of yielded cost. The new approach is applied to a microwave module (MWM) manufacturing and assembly process example.

Micron-sized subwavelength structured photonic sensors could allow critical thermo-mechanical phenomena in manufacturing processes to be monitored, while offering opportunities for fundamental understanding and better control of manufacturing processes. To implement these novel sensors into real manufacturing processes, the micro photonic sensors can be embedded at critical locations in metallic structures, which are still heavily used in hostile manufacturing environments. This paper presents the study of design, fabrication, and testing of integrated microring sensors. Various thin film optical materials were studied. Single ring resonators were designed. A new approach to fabricate metal embedded microring sensors was developed. Sensors fabricated on silicon wafers were tested and the Q factor was measured to be around 2000, the free spectrum range (FSR) was about 5 nm. Preliminary results of metal embedded sensors are also presented.

Abstract Origami-based fabrication strategies open the door for developing new manufacturing processes capable of producing complex three-dimensional (3D) geometries from two-dimensional (2D) sheets. Nevertheless, for these methods to translate into scalable manufacturing processes, rapid techniques for creating controlled folds are needed. In this work, we propose a new approach for controlled self-folding of shape memory polymer sheets based on direct laser rastering. We demonstrate that rapidly moving a CO2 laser over pre-strained polystyrene sheets results in creating controlled folds along the laser path. Laser interaction with the polymer induces localized heating above the glass transition temperature with a temperature gradient across the thickness of the thin sheets. This gradient of temperature results in a gradient of shrinkage owing to the viscoelastic relaxation of the polymer, favoring folding toward the hotter side (toward the laser source). We study the influence of laser power, rastering speed, fluence, and the number of passes on the fold angle. Moreover, we investigate process parameters that produce the highest quality folds with minimal undesired deformations. Our results show that we can create clean folds up to and exceeding 90 deg, which highlights the potential of our approach for creating lightweight 3D geometries with smooth surface finishes that are challenging to create using 3D printing methods. Hence, laser-induced self-folding of polymers is an inherently mass-customizable approach to manufacturing, especially when combined with cutting for integration of origami and kirigami.
