MODELLING OF MACHINING SYSTEMS DYNAMIC BEHAVIOUR
Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
The understanding of the static and dynamic behaviour of machine tools and the cutting processes interaction is of the main importance when designing a machining system. Moreover, the endless increase demand on quality and productivity gives even more prominence to that. Actually in machining, a central problem is the one of the stability of the cutting process. The choice of the optimal parameters of cut is a challenge that researchers and companies are facing with different approaches. The traditional method to determine these parameters consists of determining the Stability Lobe Diagram through modal analysis and cutting tests. However, in many applications, this method does not give accurate results. To face that, this thesis presents a computational model, integrated in SimMechanics (Matlab / MathWorks), of a whole machining system to analyse its behaviour and study its stability depending on the cutting parameters and machine tool configuration. The model implementation is shown in this thesis and the results obtained are analysed and evaluated.
