 Obiettivo del progetto (Objective)

'The demand for micromachining is currently increasing with the reduced device dimensions in medical, electronics, aerospace and defense fields. As nanotechnology advances in leaps and bounds, the mechanical interface of these devices becomes more critical. Unfortunately, the techniques of micromachining have not been able to keep up with the advances in nanotechnology. This disparity between the two provides an opportunity for research. To bridge this gap, new techniques in micromachining need to be created

Machine choice is a critical step in the micromachining. The rigidity of the machine tool is important as the small vibrations are amplified relative to the smaller tool diameter (e.g. vibration of 0.001 mm is a much larger fraction (1%) of a 0.10 mm end mill) and reduce the precision and damage tools

In contrast to large machine tools, meso-scale machine tools (MMT) are apt due to their small footprint, reduced energy consumption and less cost. However, the manufacture of MMT is at its nascent stage. The existing approaches considers the dynamics of machine tool subsystems individually, which can not represent the performance of machine tool in operation Hence, in this work, a generic framework is proposed for building of high performance MMTs based on coupled simulation approach that consider the dynamics of - integrated MMT, controller and machining process, without building the prototype. This approach will reduce time and cost of manufacture and increases the performance of machining The model of the existing MMT is developed by including the model of proposed novel dampers and the performance will be improved by coupled dynamics simulations. This approach is validated by physically modifying the existing design of MMT with suggested changes by simulations. From the gained knowledge, a generic framework will be developed for building of MMT and will be demonstrated The training activities include development of technical (multibody dynamics, machine tool d'
