HAMMER Time-(Prof. Julian Allwood, University of Cambridge) Feb 29 via Zoom

All dates for this event occur in the past.

Abstract: The process of Incremental Sheet Forming was invented in Japan in the 1990’s as part of a wave of research activity aiming to automate flexible processes to maintain Japanese manufacturing strength in the face of rising competition from China. I first encountered the process in 2003, was fascinated, and toured first Japan and then Europe, aiming to identify all emerging technologies in this class. The result was a fantastic demonstration of creativity, but one that led to little commercial impact, due to the challenge of scaling small test-pieces in soft aluminium to industrially relevant parts made with commercial feasibility. However, out of this global endeavour, some new science insights have developed, and some of the invention led onto processes that could scale. In our own group, our work on incremental sheet forming, flexible spinning and processes that deliberately induced through-thickness shearing led to a new form of deep-drawing, “Folding-shearing”, which is not flexible, but radically reduces material waste in trimming and is now achieving commercial success. Out of a survey of invention and development, I will attempt to identify themes where new inventiveness can lead more directly to commercial value.
