Abstract: In order to fulfil the demands of high precision manufacturing and to ensure high process reliability, new methods for theoretical investigations are required. The paper considers the state-of-the-art in burr formation modelling and simulation at first from the theoretical point-of-view, starting with numerical models and coming up to analytical models. In the second main part, new trends will be pointed out – crack initiation implementation, the |hydrostatic bowl| formulation, cutting-tool (geometry and dynamics) and friction influence and finally some aspects to consider size effects in process scaling to improve burr formation models.
Keywords: burr formation; finite element method; modelling; analytical models; fracture; size effects; ultrasonic assisted cutting; hybrid modelling; clean manufacturing; simulation; crack initiation; hydrostatic bowl formulation, cutting tools; tool geometry; tool dynamics; friction.
