Cutting of soft materials is a common daily life experience (e.g. slicing of meat and cheese) and an essential operation in many industries, healthcare (e.g. surgery) and manufacturing (e.g. paint removal) among them. By measuring the cutting forces of the tool and examining the deformation mechanisms of the work-piece, this project aims to put the cutting process on a strong scientific and technological footing. It provides an ingenious method to measure the fracture energy, i.e. specific resistance to cracking, of plastics, bulk and thin film polymer nanocomposites at different cut-depths. New knowledge gained from the project is expected to improve tool design and optimise cutting conditions to increase the cutting process efficiency.

切割软材料是一种常见的日常生活体验(例如切肉和奶酪)，也是许多行业的基本操作，医疗保健(例如外科手术)和制造业(例如油漆去除)就是其中之一。通过测量刀具的切削力和检查工件的变形机理，该项目旨在使切割过程建立在强大的科学和技术基础上。它提供了一种巧妙的方法来测量塑料、块体和薄膜聚合物纳米复合材料在不同切割深度下的断裂能，即比抗裂性。从该项目中获得的新知识有望改善刀具设计和优化切割条件，以提高切割过程的效率。
