Assessment of Cost and Energy Requirements of Electron Beam Melting (EBM) and Machining Processes

2017

Additive Manufacturing is under the spotlight as potential disruptive technology, particularly for the production of complex-shaped structural metallic components. However, the actual AM process capabilities present some limitations in achieving the strict part quality requirements imposed by the aerospace and automotive sectors. Therefore, the integration of AM and conventional manufacturing represents an emerging scenario to be investigated. In this paper, a pure machining process and a hybrid production route (based on EBM and finish machining) are compared. The influence of material usage-related factors on costs and energy demand is discussed. The results prove that, despite precise pr…

Tuning Decision Support Toolsfor Environmentally Friendly Manufacturing Approach Selection

2017

Awareness about the environmental performance of manufacturing approaches has arisen. Comparative analyses of different manufacturing approaches as well as decision support methods should be developed in the field of metal shaping processes. The present paper aims at tuning a decision support tool for identifying when mass conserving approaches (forming based) are actually preferable over machining processes for manufacturing aluminum based components. A full LCA is developed for comparing the environmental performance of forming and machining approaches as the batch size and geometry complexity hang. The impact of the used metric on the comparative results is analyzed. Results reveal that …

Benefits of entrepreneurship education and training for engineering students

2017

In the present economic situation, having knowledge of an academic subject is no longer sufficient for a new graduate. Students are increasingly required to have skills and abilities which will increase their employability, such as: the retrieval and handling of information; communication and presentation; planning and problem solving; and social development and interaction. Entrepreneurial education and training provides individuals with the ability to recognize commercial opportunities, self‐esteem, knowledge and skills to act on them. It includes instruction in opportunity recognition, commercializing a concept, managing resources, and initiating a business venture. It also includes inst…

Legal Liability of Professional Engineers: The Case of a Fire at a Shopping Center

2019

In this paper, the authors discuss the legal liabilities of the professional engineer as both the engineer of record of a project and the construction site manager. In particular, this paper analyzes the case of a fire at an end-user MV/LV substation of a shopping center in Italy, occurred a few years after maintenance works on the electrical installation. The professional engineer who had designed and overseen the construction of the substation was accused of criminal negligence. The authors through the examination of applicable technical standards, as well as of safety regulations, demonstrate that the professional engineer had acted diligently and that there was no ground for the neglige…

Purpose: Tactical analyses to distinguish between football teams that were more or less successful have been conducted up to now only by means of linear methods (like discriminant analysis). Concer...

Energy and CO2 life cycle inventory issues for aluminum based components: The case study of a high speed train window panel

2016

Abstract As materials production and transport are two relevant sectors in terms of global environmental impact, over the last years environmental impact analyses (mainly life cycle based analyses) of material replacing strategies in means of transportation were developed. Life cycle approach allows to consider the light-weighing benefit without neglecting the environmental impact of material production. In the present research energy and CO2 emissions life cycle analysis of a real case study is presented. Industrial data, experimental measurements and literature analysis were used to develop the life cycle analysis of an aluminum window panel to be assembled on an Italian high speed train.…

Guarding, guiding, gate opening: Prison officer work in a Norwegian welfare context

2017

Anne A is a prison officer, and for years, she has been working behind the walls—in low-security and high-security wings, with remand and sentenced prisoners. She says: We are there fifty per cent in order to keep an eye on them, to ensure that they stay here [in prison]. The other fifty per cent we are trying to help them. They may be drug users or have other problems, and it’s just as much our duty to help them as to watch them. And when we help, this contributes to security just as much as a locked door or an alarm.

Lean university: applying the ECRS method to improve an administrative process

2019

This paper presents a case study for an improvement method applied in “Lucian Blaga” University of Sibiu, Romania. The ECRS method has its roots in manufacturing, specifically in improvement processes. The novelty lies in applying this method in Higher Education. Considering the existing know-how in process improvements of the human resource from the University and the importance of quality in the organisation’s performance, this paper sought to focus on using one of the most important principles of lean manufacturing in the administrative sector. An observation form was designed in order to analyse the process and by using the ECRS method and brainstorming for ideas with key stakeholders, …
