In order to characterise the environmental performance of additive manufacturing (AM) processes, comparative analyses are required. Different manufacturing approaches (such as additive and subtractive ones), besides adopting different equipment, use different kinds and amounts of material. Therefore, the material-related flow has to be followed throughout the entire product life. Differences in environmental impact arise at each step of the life cycle: material production, manufacturing, use, disposal, and transportation. A life cycle-based methodology able to take due account of all the factors of influence on the total energy demand for the production of metal components is given in this paper. Decision support tools for identifying the most sustainable manufacturing route (subtractive versus AM-based approaches) are presented for different scenarios. The aim of the present paper is to contribute to the debate concerning the environmental impact characterisation of AM processes.

The objective of this research is to investigate the morphology and microstructure of the chips formed during milling of Ti-6Al-4V alloy using conventional flood coolant and sustainable dry and MQL machining conditions. It was found that the chips formed in dry machining suffered a higher degree of serration indicating higher chip temperature and ineffective cooling of the chips. The bi-modal structure of Ti-6Al-4V remained the same in the bulk part of the chips. However, phase transformations were seen for all three machining conditions at the shearing plane of the chips. The chips formed in dry machining had comparatively higher percentage of β-phase due to phase transformation. For the chips obtained in flood coolant machining, the transformed β-phase possibly returned to martensitic α-phase due to rapid cooling. The MQL machined chips had the least transformation of β-phase, indicating minimal changes in mechanical properties of the machined parts in sustainable MQL machining.

Since the liberalisation of its economy, Vietnam has emerged as a key location for investment in workforce-intensive assembly processes operation, through an available and cheap workforce. Soaring national consumption levels for goods and services generate in turn unprecedented quantities of waste to be treated locally. In 2015, governmental decision 16/2015/QÐ-TTg set a basis for a national waste legislation for mechanical and electronic equipment goods. Remanufacturing is a non-destructive, industrial reuse strategy which aims at restoring products to original specifications by reusing a maximum number of original components in their current form. It has potential to provide Vietnam with an alternative to low value-added repair activities. As Vietnam is the fourth market for motorcycles in the world, this paper presents a case study about barriers and potentials for remanufacturing from the market and customer perspective. Potential solutions for supporting industrial development are suggested.

Hard machining of brittle materials such as ceramics is a process-oriented challenge. For the machining of such materials, abrasive water jet cutting is an appropriate alternative to the commonly used diamond grinding and laser cutting processes. In abrasive water jet machining the injection technology is currently used almost exclusively. Due to the realisation of the suspension jet technology a higher cutting performance can be achieved. In this article, the known injection technology and the suspension technology are compared. To do so, the influences on the quality were examined for trimming technical ceramics. The investigation illustrates that suspension technology trims with a higher accuracy than injection technology in matters of kerf geometry but with a lower material removal rate.

The drive for ever-increasing materials and energy efficiency and associated cost savings has compelled manufacturers to adopt flexible and rapid production systems. The technical limitations and sustainability concerns of conventional unit processes and sequential process flows have led to widespread adoption of advanced manufacturing processes that exhibit cyclic nature, termed cyclic manufacturing processes. While cyclic manufacturing processes enable efficient production through reduced time-to-market, lower production costs, and shorter manufacturing process chains, relatively little attention has been paid toward characterising their associated environmental, economic, and social impacts. A holistic manufacturing process modelling framework is developed to support sustainability performance characterisation of cyclic manufacturing processes. The developed framework enables model reusability, extensibility, and composability to characterise, assess, and extract product and process sustainability information. It is applied to characterise environmental impacts of a low-cost, hybrid (additive-subtractive) process for production of polylactide (PLA) parts, and compared with a conventional subtractive process (milling).

Sustainable product development and use requires an extended life cycle of used and defective mechanical parts. Remanufacturing saves resources and helps the industry to utilise the product more efficiently. Reverse logistics is one of the most important challenges towards efficient remanufacturing. To improve this process, we propose an on-site part identification at the workshops. A fast on-site identification is essential for assisting repair shop personnel and saving time on searching for the right spare parts. Based on images taken by a mobile device our application provides various machine vision services, e.g., visual identification of used parts, already successfully tested in a sorting facility for remanufacturing parts. The mobile application provides a robust visual identification for different environments. We show that enhancing data for machine vision approaches with images from decentral sensors, i.e., mobile devices, leads to an improved identification accuracy.

In the scientific literature there is a scarcity of comprehensive and organic studies on performance indicators encompassing sustainability and their influence on decision-making. This work aims at selecting the most suitable material to manufacture an automotive component using a high pressure die casting (HPDC) process according to four classes of metrics: cost, time, quality and sustainability. The performance of three different alloys (aluminium-A380, magnesium-AZ91D and zinc-ZA8) was evaluated considering overall product life cycle aspects and process characteristics through a deterministic technique for order of preference by similarity to ideal solution (TOPSIS). Results show that the zinc alloy should be chosen on a unit mass-basis mainly thanks to its significantly superior quality and sustainability performance. This study demonstrates that the inclusion of the sustainability dimension in a multi-criteria decision analysis context challenges well-established material selection trends in the automotive industry developed during the past decades.

An efficient learning environment is required to cope with today's increasing innovation speed. Companies need methods and tools to transfer knowledge to employees in a fast way. Learners' cognitive focus should be shifted towards learning at the learning object, instead of transferring information from teaching material to the real world. Current learning environments are mostly incapable to merge physical learning tools with digital content at its point of use; therefore, the learner has to do it. Augmented reality offers the opportunity to show learning content directly on physical objects and to interact with it. Within this paper, two approaches on how to use augmented reality for teaching purposes are shown. One is for special machinery assembly of turbomachinery and the other for cocoa liquor production.

The quantum of minerals extracted from ore is critical for the success of mineral processing, hence the necessity to optimise the process flows in order to recover as much minerals as possible. The aim of this research was to identify bottlenecks and recovery-hampering factors within the comminution and flotation circuits of the concentrator plant at a platinum processing company in Zimbabwe. Modelling and simulation of the circuits were carried using Arena and Limn simulation software to optimise the process flows for improved throughput, maximum mineral recovery and enhanced efficiency and productivity. Alternative configurations of the layout of equipment were tested and compared with the original setup. The recommended reconfiguration of the circuits achieved increases of 2.97% in mineral recovery and 4 grams/ton in productivity resulting in a maximised output for the sustainable processing of platinum ore.
