- The need for a flexible and versatile workforce that is constantly learning and upgrading its skills has led to a continual demand for courses in which employees are re-trained and updated on a lifelong basis. Students and workers now have to be prepared for a labour market in which they can be expected to change jobs many times, and they need to acquire appropriate skills that are transferable and portable across sectors, countries and cultures. This paper presents a new approach to unifying a European curriculum for production engineering. The paper discusses the background, developments, module structure, testing and ongoing work that is carried out in the European Production Engineering Certification project – a two year pilot project granted by the European Union Programme Leonardo da Vinci.

Grinding and fine finishing of future automotive powertrain components
- 2021
-
In: CIRP Annals - Manufacturing Technology. - : Elsevier BV. - 1726-0604 .- 0007-8506. ; 70:2, s. 589-610
-
Journal article (peer-reviewed)abstract
- The automotive industry is undergoing a major transformation driven by regulations and a fast-paced electrification. A critical analysis of technological trends and associated requirements for major automotive powertrain components is carried out in close collaboration with industry – covering the perspectives of OEMs, suppliers, and machine builders. The main focus is to review the state of the art with regard to grinding, dressing, texturing and fine-finishing technologies. A survey of research papers and patents is accompanied by case studies that provide further insights into the production value chain. Finally, key industrial and research challenges are summarized.

Influence of the minimum chip thickness on the obtained surface roughness during turning operations
- 2014

In: Procedia CIRP. - : Elsevier BV. - 2212-8271. ; 13, s. 67-71
-
Conference paper (peer-reviewed)abstract
- Considerable efforts have been put into analyzing the obtained surface roughness during turning operations. However, knowledge is still lacking on how to model the arithmetic mean surface roughness Ra through using a general model applicable for all workpiece materials and process parameters. Further, the influence of the minimum chip thickness on the obtained surface roughness needs to be clarified. This article presents a new model for predicting the Ra surface roughness during turning operations. The model is based on physical and empirical knowledge of the turning process and has been experimentally validated through turning Al-SiCp MMC, cast iron, conventional- and stainless steels, as well as Ti6Al4V. The obtained results show great potentials with an average error of 6.7% even though errors as large as 16.6% were obtained for some cases.

Machining SiC fibre reinforced metal matrix composites – How do different matrix materials affect the cutting performance?
-
In: CIRP Annals. - 0007-8506.
-
Journal article (peer-reviewed)abstract
- SiC fibre reinforced metal matrix composites find widespread application but show major machining difficulties due to significant variations in constituents' properties. In this sense, while the SiC fibre plays significant strengthening effects, the properties mismatch between the brittle fibre and ductile matrix materials becomes important in their machining performance. Through machining tests, SiC fibre reinforced MMCs with Al (soft) and Ti (hard) matrix alloys are evaluated, showing the variation of interaction between inserts and fibres in cutting due to the different matrix properties. This leads to less tool wear but compromised surface integrity in Al-based composite than in Ti-based one.
