Development of manufacturing technologies for sheet metal processing with minimal waste, and engineering design of machines to implement these processes. Almost 25% of emissions associated with car manufacture are due to the production of sheet metal for vehicle bodies, with nearly half of these emissions related to waste: almost half the sheet metal purchased is trimmed off and scrapped. The folding-shearing process for "shrink" features previously invented in the Department has shown a reduction in waste by at least 75%, and hence a reduction of 25-40% in the embodied emissions of car body production. The extension of the folding-shearing methodology to "stretch" corners, through the new tooling examined in this PhD, could ultimately extend this benefit to a much greater range of car-body parts, making it truly transformative in the field of sheet forming, a major global industry.

开发最少浪费的金属板材加工制造技术，以及实施这些工艺的机器工程设计。与汽车制造相关的排放中，近25%源于车身金属板材的生产，其中近一半与废物有关：几乎一半购买的金属板材被修剪和报废。该部门以前发明的折叠剪切法可减少至少75%的浪费，从而减少25%-40%的车身生产中的实际排放量。通过本博士研究的新工具，将折叠剪切方法扩展到“拉伸”拐角，最终可能会将这一优势扩展到更广泛的汽车车身部件，使其在板材成形领域真正实现变革，板材成形是全球主要行业。
