Data-driven modelling in the era of Industry 4.0: A case study of friction modelling in sheet metal forming simulations

August 8, 2018

Reading Time: < 1 minute Abstract With growing demands on quality of produced parts, concepts like zero-defect manufacturing are gaining increasing importance. As one of the means to achieve this, industries strive to attain the ability to control product/process parameters through connected manufacturing technologies and model-based control systems that utilize process/machine data for predicting optimum system conditions without human intervention. […]

Introductory study of sheet metal forming simulations to evaluate process robustness

June 29, 2018

Reading Time: < 1 minute Abstract The ability to control quality of a part is gaining increased importance with desires to achieve zero-defect manufacturing. Two significant factors affecting process robustness in production of deep drawn automotive parts are variations in material properties of the blanks and the tribology conditions of the process. It is imperative to understand how these factors […]

Urban Mining as a Case for PSS

June 15, 2016

Reading Time: < 1 minute Abstract Reports about the depletion and pollutant of the earth by human interference and the increasing need for urbanised areas require us to think differently about how we go about achieving this increased urbanisation. In this context, urban mining, where demolition sites are mined for increased recycling and value extraction. Due to high specialisation of […]
